Question details

The user needs to log into their Microsoft account but cannot proceed because the Authenticator app is not displaying the required two-factor authentication codes after a password change.

Product: Microsoft Authenticator
Device & OS: not provided
Scenario: Attempting to sign in to a Microsoft account after recently changing the account password.
Observed behavior: Microsoft repeatedly prompts for two-factor authentication, but the Authenticator app fails to display or generate any verification codes.

Before you start

Check if you have an alternative recovery email or phone number linked to your Microsoft account, and ensure your mobile device has a stable internet connection.

Solution 1Recommended

Use an Alternative Verification Method

Bypass the Authenticator app by requesting a security code via your registered recovery email or phone number.

Select alternative sign-in

On the Microsoft sign-in screen, click on 'Sign in another way' or 'I don't have my Authenticator app' when prompted for the verification code.

Choose a recovery option

Select an available alternative verification method from the list, such as a recovery email address or an SMS to your registered phone number.

Enter the code

Retrieve the verification code sent to your email or phone and enter it on the login screen to regain access to your account.

Solution 2

Restart Device and Check App Configuration

Refreshing the device and app settings can resolve temporary syncing issues preventing codes from appearing.

Solution 3

Contact Official Microsoft Support

If all recovery methods fail, you must contact Microsoft Support to manually recover your account, as community forums cannot access private data.

Frequently Asked Questions

Why did my Authenticator codes stop showing after a password change?

Changing your Microsoft account password can sometimes invalidate the existing security token on your device, causing the Authenticator app to lose sync and stop displaying valid verification codes.

How can I regain access if I don't have a recovery email set up?

If you don't have alternative verification methods available, you will need to fill out the Microsoft Account Recovery form online. You must provide enough accurate historical information about the account to prove your identity.

Can community moderators help me reset my Microsoft Authenticator?

No. Community moderators and forum support staff do not have access to private account information or the backend authentication systems. You must use official Microsoft recovery channels to resolve sign-in issues.
