Follow these steps to regain access when MFA codes are not arriving and Windows sign-in depends on a Microsoft account:
- On another device (phone browser or another PC), go to the Microsoft account sign-in page and try to sign in with the same account used on the laptop.
- When prompted for a verification code, carefully check that the code is being sent to the correct security info:
- Primary alias or an email/phone that was explicitly added as a way to verify sign-in.
- Make sure the email address shown (first two characters) matches the registered one.
- Check the email account used for MFA:
- Look in Inbox and Junk/Spam for a message from
@accountprotection.microsoft.com. - Mark
@accountprotection.microsoft.comas a trusted sender so future codes arrive in the inbox.
- Look in Inbox and Junk/Spam for a message from
- If the registered email is another Microsoft account (for example, an @outlook.com, @hotmail.com, @live.com, or @msn.com address), use private browsing so both accounts can stay signed in:
- Open a browser in privacy/InPrivate mode.
- Sign in to the first Microsoft account (the one that needs the code) and proceed until it asks for the verification code. Leave this tab open.
- Open a new privacy/InPrivate window (for example, Ctrl+Shift+P in Microsoft Edge).
- In the new window, sign in to the alternate Microsoft email account where the code is sent and read the message from the Microsoft account team.
- Copy the verification code and return to the first window to enter it.
- If codes still do not arrive:
- Avoid repeatedly requesting codes, as excessive requests can cause temporary blocking of code delivery.
- Check whether the account might be temporarily blocked due to unusual activity; in that case, waiting for the block to clear may be required.
- If access to the registered security email/phone is lost:
- Start sign-in to the Microsoft account and, at the “Verify your identity” prompt, choose I don't have any of these.
- Follow the steps to replace security info. After replacement, there is a 30‑day wait before full sign-in is allowed. If the old security info becomes available during that period, it can still be used to sign in, which cancels the pending change.
- If none of the above works and sign-in to the Microsoft account is still not possible, use the sign-in helper and/or account recovery form from another device to attempt recovery, as Windows sign-in with that account depends on successfully authenticating the Microsoft account:
- Use the Sign-in helper to diagnose common sign-in issues.
- If necessary, follow guidance in Help with the Microsoft account recovery form and submit the recovery form.
If sign-in to the Microsoft account cannot be recovered, creating a new local or Microsoft account on the device may be required, which can involve data loss for files tied only to the locked profile.
