A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
This is usually a sign-in verification loop. Use another verification method or replace the broken one.
- Go to your Microsoft account security page and select Update info.
- Choose a sign-in method that still works. If none work, choose I don't have any of these to replace your security info.
- If the account is asking for a code sent to another Microsoft email address, open the first account in one private browsing window, then open a second private browsing window and sign in to the alternate email account there to get the code.
- If Microsoft Authenticator shows Authentication did not complete, check these items on the phone:
- Unlock the Microsoft Authenticator app.
- Enable notifications for the app.
- Update to the latest version of Microsoft Authenticator.
- Switch between Wi‑Fi and mobile data.
- Make sure date and time are correct on the device.
- If the account was blocked because of unusual sign-in activity, follow the sign-in screen prompts to receive a security code and enter it. A trusted device or usual location can also help regain access.
- If the account is locked, sign in at
https://account.microsoft.comto request a security code. Any phone number that can receive text messages can be used; it does not need to be associated with the account. - If the account is an Outlook.com account and it still cannot be unblocked, use the Sign-in Helper.
If the sign-in page does not show Next, the account may be locked due to suspicious activity or a Terms of Use issue. In that case, use the aka.ms/ link shown in the sign-in window and submit the reinstatement form. After submission, wait for the Microsoft Online Safety support agent response and do not submit multiple requests.
