Anvil Solutions — Microsoft 365 Sign-in Guides

Signing In to Your Work Account

What is changing. Microsoft is switching off sign-in codes sent by text message on 1 February 2027. Instead you will approve sign-ins on your phone, or use your face, fingerprint or a PIN. It is quicker than typing a code, and much harder for anyone to trick you out of.

1 Feb 2027 text message codes stop working
START

What do you want to do?

Not sure? Start here. Most people need two things, in this order:

1. Microsoft Authenticator on your phone — this is the main one, and it is what replaces text messages.

2. A backup on your computer — three minutes, and it means losing your phone is never a crisis. On most work computers this is already set up, so it is often just a quick check.

Everything else on this page is optional or for later.

Questions people ask before startingopen
QuestionAnswer
Do I have to use my personal phone?If you would rather not, tell us. There are other options, including signing in from your work computer instead.
Can you see what is on my phone?No. We can see the make, model and operating system version, nothing else. There is a full answer in Register Your Phone for Work Access.
What if I lose my phone?Contact us and we will get you back in the same day. Setting up a backup on your computer means you may not even need to call.
Do I have to do this now?Text message codes stop working on 1 February 2027. Doing it now takes five minutes; doing it in a rush later is harder.
Will I have to do this every time I sign in?No. This is a one-off setup. After that, signing in is quicker than it is today.

Set Up Microsoft Authenticator

iPhone  |  About 5 minutes

What this is for. Microsoft is switching off sign-in codes sent by text message on 1 February 2027. The Microsoft Authenticator app replaces them. It is quicker, and much safer.

You will need: your iPhone, and a computer.

1Install the app

  1. On your iPhone, tap or type this link: aka.ms/authapp
  2. Install Microsoft Authenticator.
  3. Already have it? Check for an update and install it.

If the app is out of date, this will not work. Check for an update first.

Check you are downloading the right app. Searching the App Store for “Microsoft Authenticator” usually shows other companies’ apps first, marked Ad. Some of them use Microsoft’s name and logo in their pictures, so they look convincing.

Before you tap Get, check all three: the publisher says Microsoft Corporation, there is no “Ad” label, and the name is exactly Microsoft Authenticator — not “Authenticator App” or anything similar.

The safest way is to use the link above rather than searching. It takes you straight to the correct app.

A real search. The first result is an advert for a different company’s app. The genuine one is second — note Microsoft Corporation underneath it.

2Open your security settings

  1. On your computer, go to mysignins.microsoft.com/security-info
  2. Sign in with your work email address.
  3. Click Add sign-in method.
  4. Choose Microsoft Authenticator.
  5. Click Next on the screens that follow.
  6. A square QR code appears. Leave it on screen.

3Scan the code

  1. Open Microsoft Authenticator on your iPhone.
  2. Tap the + at the top.
  3. Tap Work or school account.
  4. Tap Scan a QR code.
  5. Tap OK if it asks to use your camera.
  6. Point your phone at the QR code on your computer.

4Say yes to notifications

Important. If your iPhone asks whether Authenticator can send notifications, tap Allow. Without this, the app cannot tell you when you are signing in, and nothing will happen.

Tapped the wrong one? Go to Settings → Authenticator → Notifications and turn on Allow Notifications.

5Finish the test

  1. Your computer shows a two-digit number.
  2. A notification appears on your phone. Tap it.
  3. Type the number into the app.
  4. Tap Yes.

Type the number from your computer, then tap Yes.

If a prompt appears when you are not signing in, tap “No, it’s not me”. That tells us someone else may be trying to use your account, and we will look into it straight away. Never approve a request you did not expect.

Done. Next time you sign in, you will get a notification on your phone. Tap it, type the number from your screen, and you are in.

Make Microsoft Authenticator Your Default

If you already sign in with a text message  |  About 3 minutes

What this is for. If you already receive a code by text message when you sign in, you can keep that for now — but it is worth adding the Microsoft Authenticator app and making it your default.

Text message codes stop working on 1 February 2027, so the sooner you switch, the less you have to think about it.

1Add the app first

If you have not already installed and set up Microsoft Authenticator, do that first. Use the guide for your phone:

You will be asked to verify yourself part way through. That is normal — use your usual text message code. It only happens this once.

2Change your default

  1. On your computer, go to mysignins.microsoft.com/security-info
  2. Sign in with your work email address.
  3. Near the top you will see Default sign-in method.
  4. Click Change next to it.
  5. Choose the Microsoft Authenticator option. Depending on how your account is set up, this reads either Microsoft Authenticator — notification or App based authentication or hardware token — code. Either is correct.
  6. Click Confirm.
Change default method dialog with the Microsoft Authenticator option selected
Pick the Microsoft Authenticator option, then Confirm. The exact wording varies.

Done. From now on you will get a notification on your phone instead of a text message.

Should I delete my phone number?

No — leave it there for now. Keeping your phone number as a backup means you are not stuck if something goes wrong with the app. We will let you know when it is time to remove it.

If something goes wrongopen
ProblemWhat to do
I cannot see “Default sign-in method”You may need to scroll up. It sits above the list of your sign-in methods.
Microsoft Authenticator is not in the listThe app has not been added to your account yet. Go back to Step 1.
I still get text messagesSign out completely and back in again. If it continues, contact us.

Worth doing next. Set up a second way to sign in, so a lost or replaced phone is never a problem. See Set Up a Passkey on Your Computer — it covers Windows and Mac.

Register Your Phone for Work Access

iPhone or Android  |  About 3 minutes

What this is for. Registering your phone lets you use work email, Teams and OneDrive on it. Without it, those apps may refuse to sign in or keep asking you to try again.

You will need: Microsoft Authenticator already set up on your phone. If you have not done that yet, do it first.

1You may already be done

If you have added your work email to Outlook on your phone and it is working, your phone is probably registered already. Check first:

  1. Open Microsoft Authenticator.
  2. Tap the three lines (☰) in the top left corner.
  3. Tap Settings.
  4. Look for Device Registration.

If it already shows your work email address, there is nothing more to do.

2How to register

  1. Open Microsoft Authenticator.
  2. Tap the three lines (☰) in the top left corner.
  3. Tap Settings.
  4. Tap Device Registration.
  5. Tap Register your device.
  6. Sign in with your work email address and password.
  7. Approve the sign-in when your phone asks.

Done. Device Registration should now show your work email address. You can close the app and open Outlook or Teams.

What we can and cannot see

This is the question we get asked most, so here is a straight answer.

  • We can see: the make and model of your phone, which version of its operating system it runs, and that it is registered.
  • We cannot see: your photos, your personal messages, your browsing, your apps, or your call history.
  • If you leave, or your phone is lost: we can remove access to work email and files. We cannot wipe your personal data.

One exception. A few organisations use fuller phone management, which works differently and does more. If we have asked you to install an app called Company Portal, use that guide instead of this one — and ask us if you are unsure which applies to you.

Set Up a Passkey

iPhone or Android  |  About 5 minutes

What this is for. A passkey lets you sign in with your face or fingerprint. There is no code to type at all.

It is also the safest option available. A passkey only works on the real Microsoft sign-in page. If you were ever tricked onto a fake one, it simply would not work — so it cannot be stolen the way a code can.

You will need: Microsoft Authenticator already set up on your phone. If you have not done that yet, do it first.

1Check your app is up to date

  1. On your phone, tap or type this link: aka.ms/authapp
  2. If an update is offered, install it.

This step matters. Passkeys do not work on older versions of the app. If the passkey option is missing later on, this is why.

2Start the setup

  1. On your computer, go to mysignins.microsoft.com/security-info
  2. Sign in with your work email address.
  3. Click Add sign-in method.
  4. Choose Passkey in Microsoft Authenticator.

Careful — the first two options look almost the same.

Choose “Passkey in Microsoft Authenticator” — the first one.

Do not choose “Passkey” on its own — that one is for setting up a passkey on a computer, which is a separate guide.

Picked the wrong one? Close the window and start again. Nothing will be broken.

Add sign-in method list showing Passkey in Microsoft Authenticator above plain Passkey
Choose the first option, not the second.

3Confirm on your phone

  1. Follow the instructions on screen.
  2. When your phone asks, confirm with your face, fingerprint or phone PIN.
  3. Give the passkey a name you will recognise, such as My iPhone.

What you should see when it has worked.

Done. Next time you sign in, choose the passkey option and confirm with your face or fingerprint. No code to type.

If your password manager pops up

Your password manager may offer to save the passkey for you. It appears in its own window, separate from the Microsoft one. Close it without saving.

Your password manager already holds your password. If it holds your passkey too, then everything needed to get into your account sits in one place — which defeats the point. Just close the pop-up and carry on with the Microsoft window behind it.

Already saved one there by mistake? Nothing is broken, but please let us know so we can tidy it up.

If something goes wrongopen

Set Up a Passkey on Your Computer

Windows and Mac  |  About 3 minutes

What this is for. This adds a second way to sign in, using your computer instead of your phone. You sign in with your face, your fingerprint, or a PIN. There is no code to type.

Why this matters. Everything on your phone disappears with your phone. If you lose it, break it or upgrade it and your phone was your only way in, you would have to call us to get back into your account. A way in from your computer means that never happens — and for most people it is already set up. The check below takes ten seconds.

1Check first — you may already have this

If you sign in to your work computer with a PIN, this is already set up. There is nothing more for you to do on that computer, and you can stop reading here.

Most work computers are already connected to your organisation, and Windows sets this up as part of that. To be sure, take ten seconds to check:

  1. Click Start, then Settings.
  2. Click Accounts.
  3. Click Access work or school.
  4. Look for a line saying Connected to your organisation’s Microsoft Entra ID.
What you seeWhat to do
Connected to your organisation, and you sign in with a PINYou are done. Nothing further needed.
Connected to your organisation, but you sign in with a passwordFollow the Windows steps below to add a PIN.
Not connected to your organisationContact us before going further — this may not be a managed work computer.
You use a MacSkip the Windows section and go to Mac below.

Want to add your face or fingerprint as well? If your computer supports it, you can add those alongside your PIN using the Windows steps below. It is optional — the PIN alone is enough.

You will need: your work computer. Use the one you work on every day.

2Windows

On Windows this is called Windows Hello.

  1. Click Start, then Settings.
  2. Click Accounts.
  3. Click Sign-in options.
  4. Pick one:
    • Facial recognition — if your computer has a Windows Hello camera
    • Fingerprint — if it has a fingerprint reader
    • PIN — works on any computer
  5. Click Set up and follow the instructions.
Windows Settings open at Accounts, Sign-in options
Settings → Accounts → Sign-in options.
Windows Hello PIN setup dialog
Choosing a PIN.

You may see a message saying your organisation requires Windows Hello. That is expected — click OK and carry on.

Then you can save passkeys on this computer

Once your PIN is set, Windows can store passkeys. You will find them under Settings → Accounts → Passkeys.

Windows passkeys page indicating a PIN is needed first
Before the PIN is set, Windows tells you it is needed first.

When you create a passkey for your work account, Windows asks where to keep it.

Windows dialog confirming the passkey will be saved to this Windows device
Check it says saved to your Windows device, then click Continue.
Windows Saved passkeys list showing the new passkey
Afterwards it appears under Saved passkeys.

Is a PIN really safe? Yes — safer than a password here. Your PIN only works on this one computer. It is useless to anyone who does not physically have your machine.

A password is different. It works from anywhere in the world, which is why passwords have to be long and complicated.

Choosing your PIN: use at least 6 digits, and do not reuse your bank PIN, your phone PIN, or your date of birth.

3Mac

On a Mac you create a passkey that unlocks with Touch ID. You get a choice of where to keep it, and both options work.

Where to save itWhat that means
On this MacStays on this computer only. Straightforward, and the right choice if you only use one Mac.
iCloud KeychainSyncs to your other Apple devices, so the same passkey works on your iPhone and iPad too. Choose this if you use several Apple devices.
  1. Go to mysignins.microsoft.com/security-info
  2. Sign in with your work email address.
  3. Click Add sign-in method.
  4. Choose Passkey.
  5. When your Mac asks where to save it, pick either on this Mac or iCloud Keychain — see the table above.
  6. Confirm with Touch ID.
  7. Name it after the computer, for example My MacBook.

If you already have another passkey and sign-in offers the wrong one, look for Other options or Try another way on the sign-in screen and choose the one you want. Having several passkeys is fine — you just occasionally need to tell it which to use.

macOS dialog asking where to save the passkey
Mac: choose where to keep it. Both iCloud Keychain and saving on this Mac work.
macOS Touch ID confirmation prompt
Then confirm with Touch ID.

Done. You now have two ways to sign in — your phone and your computer. If you lose one, you can still get in with the other.

If something goes wrongopen
ProblemWhat to do
Windows: the options are greyed outContact us. Your computer may need a setting changed first.
Windows: face or fingerprint is missingYour computer does not have the hardware. Use a PIN instead — it works just as well.
Mac: it saved somewhere unexpectedNot a problem. Let us know and we will tidy it up.
Mac: Touch ID is not offeredOlder Macs may not support this. Contact us and we will sort out another option.
Mac: it keeps asking for a security key I do not haveAnother passkey is being offered instead of yours. Choose Other options on the sign-in screen, or contact us and we will tidy up the old one.
I share this computer with someoneContact us before setting this up.
This is not a work computerContact us. We only set this up on computers we manage.

Do this as well as your phone, not instead of it. Your computer works when your phone does not, and your phone works when you are away from your desk. Having both is what stops you being locked out.

Need help? Contact the Anvil Solutions helpdesk on 09 579 5432 or support@anvil.net.nz. If you are locked out completely we can issue a temporary pass that lets you sign in once and set things up again — being stuck is never permanent.

Getting a New Phone

What to do before and after you swap  |  About 5 minutes

Read this before you wipe or hand back your old phone.

Your work sign-in does not move across to a new phone by itself. It is not part of an iCloud or Google backup, even if the app itself reappears. If you set up the new phone and get rid of the old one first, you may not be able to sign in.

1The easy way — while you still have the old phone

  1. Set up Microsoft Authenticator on your new phone, following the normal guide.
  2. If you use a passkey, set that up on the new phone too.
  3. Check it works — sign out of your work account on a computer, then sign back in using the new phone.
  4. Only then wipe or hand back the old phone.

Doing it in this order takes five minutes and means nothing can go wrong.

2If the old phone has already gone

You are not locked out permanently. Try these in order.

First — sign in from your computer

If you sign in to your work computer with a PIN, face or fingerprint, use that to sign in as normal. Then add Microsoft Authenticator to your new phone from mysignins.microsoft.com/security-info. This is the quickest route, and it needs no help from us.

Then — contact us

If your phone was your only way in, contact the Anvil helpdesk. We will give you a temporary pass — a code that lets you sign in once, so you can set up your new phone straight away. We will need to check who you are first, so please call rather than email if you can.

3Tidy up afterwards

Once your new phone is working, remove the old one so it cannot be used.

  1. Go to mysignins.microsoft.com/security-info
  2. Find the entry for your old phone.
  3. Click Delete.
Security info page listing sign-in methods with the default at the top
Your sign-in methods. Check the default at the top is the one you want to use.

Make sure the new phone works before deleting the old one. If you delete the wrong entry you may lock yourself out.

Lost or stolen phone? Tell us straight away — before anything else. We will remove it from your account so nobody else can use it, and get you signed in again.

Common questionsopen
QuestionAnswer
Does my iCloud or Google backup restore it?No. Work accounts are not included, even if the app itself reappears with your account name showing. You still have to set it up again.
Can I have both phones set up at once?Yes, and that is the easiest way to change over.
I only changed my SIM, not the phoneNothing to do. This is linked to the phone, not the number.
I have the same phone but reset itTreat it as a new phone and set it up again.
Do I need to register the new phone as well?Yes, if you use work email, Teams or OneDrive on it. See Register Your Phone for Work Access.

How to avoid this next time. Set up a second way to sign in that is not on your phone — a way in from your work computer. Then a new phone is never a problem: you sign in from your computer and set the phone up yourself, without calling anyone.

Need help? Contact the Anvil Solutions helpdesk on 09 579 5432 or support@anvil.net.nz. If you are locked out completely we can issue a temporary pass that lets you sign in once and set things up again — being stuck is never permanent.

Notifications Not Working

iPhone and Android  |  About 2 minutes

The usual cause. You set up Microsoft Authenticator, you try to sign in, and nothing happens on your phone. Nine times out of ten the app has not been given permission to send notifications. Below is how to fix it.

1First, check the obvious

  • Is your phone on and unlocked?
  • Is it connected to Wi-Fi or mobile data? The app needs a connection to receive the request.
  • Is your phone in Do Not Disturb or Focus mode? That can hold the notification back.

You can always sign in without the notification. On the sign-in screen look for an option such as Use a verification code or I cannot use my Microsoft Authenticator app right now, then open Microsoft Authenticator and read the six-digit code next to your work account. That works even with notifications switched off.

2iPhone — turn notifications on

  1. Open Settings.
  2. Scroll down and tap Authenticator.
  3. Tap Notifications.
  4. Turn on Allow Notifications.
  5. Make sure Lock Screen, Notification Centre and Banners are all ticked.

3Android — turn notifications on

  1. Open Settings.
  2. Tap Apps, then Authenticator.
  3. Tap Notifications and turn them on.

4Android — if notifications arrive late, or only sometimes

This one catches a lot of people, especially on Samsung phones. Android saves battery by pausing apps it thinks you are not using. That can delay a sign-in request by minutes, or stop it arriving at all.

  1. Open Settings.
  2. Tap Apps, then Authenticator.
  3. Tap Battery.
  4. Choose Unrestricted.

On some phones this is called Allow background activity or Do not optimise. If you cannot find it, contact us and we will talk you through it.

Still nothing?open
What is happeningWhat to do
