How to receive verification code

Try these checks in order:

1. Check the correct destination.
   • Email codes are only sent to the primary alias or another email added as a sign-in verification method.
   • If using phone, confirm the shown ending digits match the correct number.
2. Check junk or spam.
   • Verification emails can go to Junk.
   • Valid verification emails come from @accountprotection.microsoft.com.
   • Mark @accountprotection.microsoft.com as a trusted sender.
3. Avoid repeated requests.
   • Too many code requests can cause Microsoft to temporarily stop sending codes.
4. Check for temporary security blocks.
   • If sign-in activity looks unusual, code delivery can be temporarily blocked.
   • Heavy compromised traffic from a geographic location can also delay delivery and usually resolves automatically after some time.
5. If using SMS:
   • Make sure the phone does not block texts from unknown numbers.
   • If prompted, select I don't have a code to send another one.
   • Check that the message inbox is not full.
   • VOIP numbers cannot be used for sign-in or verification codes; a mobile number is required.
6. If the verification email is another Microsoft email account such as @outlook.com, @hotmail.com, @live.com, or @msn.com:
   • Open a browser in privacy mode and sign in to the first account.
   • When asked for the code, keep that window open.
   • Open a second privacy-mode window.
   • Sign in to the alternate email account there and get the code.
   • Return to the first window and enter the code.
7. Verify or update security info.
   • Go to the Security page and select Update info or Manage how I sign in.
   • Add a new way to sign in or verify if needed.
   • Do not change all security info at the same time, because the account may be restricted for 30 days.
8. If access to the old phone or email is lost:
   • At the Verify your identity prompt, select I don't have any of these and follow the prompts to replace security info.
   • If all security info is replaced, sign-in is blocked for 30 days.
9. If still blocked from signing in:
   • Use the Sign-in helper.
   • Support can help with troubleshooting, but support agents cannot send verification codes or change account details.
