A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
If this is a personal Microsoft account and there is no access to the Authenticator app, the app cannot be reset by support.
Use one of these recovery paths:
- If another sign-in or verification method is still available:
- Go to the Advanced security options page.
- Select Add a new way to sign in or verify.
- Confirm the new method with the security code sent to it.
- Remove the old Authenticator/security method that is no longer accessible.
- If the password is known but there is no access to any security methods:
- Start signing in to the Microsoft account.
- At Verify your identity, select I don't have any of these.
- Follow the prompts to replace the security info.
- After replacement, there is a 30-day wait before sign-in is allowed.
- If the password is not known and there is no access to any security methods:
- Use the account recovery form.
If verification codes are not arriving, also check:
- junk email for messages from @accountprotection.microsoft.com
- whether too many repeated code requests were made
- whether the account is temporarily blocked due to unusual activity
- whether the phone blocks texts from unknown numbers
- whether the registered number is a VOIP number, which cannot be used for sign-in verification
If sign-in is still blocked, use the Sign-in helper or Contact Microsoft Support. Support agents cannot send verification codes, password reset links, or change account details.
