Try these Windows 11 checks in order:
- Restart the laptop first A restart can clear temporary sign-in problems. If Windows Update shows pending updates, use Update and restart.
- Install the latest Windows updates There is a documented Windows 11 issue where Microsoft account sign-ins can fail in apps and repeatedly prompt for sign-in even when the device is online. This was resolved by later Windows updates. Install the latest updates available for the device.
- Use the Microsoft account sign-in helper If the account itself is having trouble, use the Sign-in Helper tool. It checks the email address or phone number used to sign in and identifies common account problems.
- If the password is correct but sign-in still keeps failing, recover the account
Follow this path:
- Enter the email address, phone number, or Skype name used to sign in.
- Choose where to receive the security code.
- Enter the code.
- Set a new password if prompted. Also verify the sign-in name is exactly correct, including the email domain such as .com vs .co.uk.
- If verification prompts or security emails keep appearing Check the verification-code troubleshooting guidance. Repeated prompts can happen when sign-in verification is not completing correctly.
- If Microsoft Store purchases are asking for sign-in every time On Windows 11, open Microsoft Store > Profile > App settings > Purchase sign-in and turn it On. This only affects that device and applies to certain in-app purchases.
- If the issue is only with Windows sign-in or profile behavior
Use the Windows sign-in troubleshooting options for:
- forgotten PIN
- password reset
- verification code issues
- corrupted profile issues
If the problem has been happening for two months even after updates and restart, use Contact Support from Microsoft Support and report that the device repeatedly forgets app and site sign-ins and sends “unregistered device” alerts.
