Microsoft Authenticator not showing verification code

If the account is present in Microsoft Authenticator but no code appears, use the recovery path based on what access is still available:

1. Check whether another sign-in method is available.
   • At the sign-in prompt, select Try another verification method or I don't have any of these if shown.
   • Use an alternate email or phone number already connected to the account.
2. If verification codes are being sent by email instead of the app:
   • Check the correct mailbox.
   • Check the junk folder.
   • Valid verification emails come from @accountprotection.microsoft.com.
   • If the alternate email is another Microsoft account, open the first account in one privacy-mode window and the alternate email account in a second privacy-mode window so both accounts stay signed in.
3. If SMS is an option:
   • Make sure the phone can receive texts from unknown numbers.
   • If prompted, select I don't have a code to request another one.
   • VOIP numbers cannot be used for sign-in or verification codes; a mobile number is required.
4. If access to some security info is still available:
   • Go to the Advanced security options page and select Add a new way to sign in or verify.
   • Confirm the new email or phone with the code sent to it.
   • Then remove the security method that no longer works.
   • Do not change all security info at the same time, or the account may be restricted for 30 days.
5. If access to all security info is lost but the password is known:
   • Start sign-in.
   • 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.
6. If the password is also unavailable:
   • Use the account recovery form: Recover account
7. If repeated requests were made already:
   • Stop making repeated code requests.
   • Temporary blocks can happen because of unusual activity, high request volume, or traffic conditions.
   • Wait at least 24 hours; if needed, wait longer, up to 1 week.
   • Trying another network can also help.
8. If this is a work or school account and the app no longer has a valid registration:
   • Another global admin may need to reset MFA registration.
   • If there is no other admin, contact Microsoft Support for the business account.
9. If no method works:
   • Use the sign-in helper tool: Sign-in helper
   • Microsoft support agents cannot send verification codes or change account details, but they can route to the correct support option.
