A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
The displayed number is normally entered into the New sign-in request inside Authenticator, but if no approval request appears because the account is not fully configured, use another registered method or have the Authenticator registration reset.
Try the number-matching request
- Leave the sign-in screen showing the number.
- Open Authenticator by tapping its New sign-in request notification, rather than starting another sign-in from the account tile.
- Unlock Authenticator if prompted.
- Enter or select the number displayed on the original sign-in screen, then select Approve.
That is the expected number-matching flow; the number appears on one screen and the approval request appears inside Authenticator on the phone.^1^
If Authenticator only returns to a login page and never displays New sign-in request, use the applicable recovery path below.
If another verification method is available
On the sign-in page, select Other ways to sign in, Sign in another way, or I can’t use my Microsoft Authenticator app right now, then choose an already-registered method such as email, passkey, text, or phone call.
Do not remove the Authenticator account until another working verification method is available; removal can leave the account completely inaccessible.
Work or school account
Contact the organization’s IT administrator and ask them to reset the Authenticator registration:
- Sign in to the Microsoft Entra admin center as at least an Authentication Administrator.
- Go to Entra ID → Users.
- Select the affected user and then Authentication methods.
- Select Require re-register MFA.
- Sign in again and register Authenticator from the beginning.
This action deletes the user’s registered Authenticator apps and other listed MFA methods, requiring fresh registration.^2^
If the organization supports a Temporary Access Pass, the administrator can issue one so the user can sign in and register a new authentication method.^3^
If this is the only administrator account and no other authentication method works, contact Microsoft business support for tenant-access recovery. Do not create or delete accounts while access is being recovered.
Personal Microsoft account
Select another verification method if one is offered. After regaining access:
- Open the Microsoft account Security page.
- Select Manage how I sign in.
- Select Add a new way to sign in or verify.
- Add and verify another method before changing the existing Authenticator registration.^4^
If no method works, use Microsoft account recovery/support. In Authenticator, open the top-level menu and select Send feedback first so diagnostic logs are captured.^5^
Only approve a request that corresponds to a sign-in you initiated. Deny any unexpected number-matching request.
