Microsoft Authenticator

Question

How do use Microsoft Ooutlook as my Microsoft Authenticator?

Answer 1

Hi, @Vicki Moore

Do you mean you want to use the Outlook app on your phone to approve Microsoft account sign-in requests, instead of using the Microsoft Authenticator app?

If yes, are you using an Android phone or iPhone?

Microsoft also has a guide here:

Thanks!

Answer 2

For a personal Microsoft account, Outlook mobile can be used for sign-in notifications or one-time sign-in codes, but Microsoft Authenticator is the only mobile app for personal account users if the goal is to use Microsoft’s authenticator app experience.

If Outlook mobile is supported for the sign-in method being used, turn it on in the Outlook mobile app:

1. Open Outlook mobile.
2. Go to Settings > Accounts > select the account.
3. Select Account > Sign-in requests.
4. Turn on Allow sign-in requests.

To use Outlook mobile to get a one-time code:

1. Open Outlook and tap the Home icon.
2. Tap Settings.
3. Under General, tap Accounts and select the account.
4. Tap Sign-in requests.
5. Copy the displayed code.
6. Paste that code on the sign-in page.

Important details:

• If Microsoft Authenticator is already installed, Outlook may show an error saying that Authenticator must be used to sign in.
• Outlook for iOS does not support personal accounts for this feature. For personal accounts, the supported mobile app is Microsoft Authenticator.
• For passwordless sign-in on a Microsoft account, set up an authenticator app first, then go to Additional security options and turn on Passwordless account.
