Hello ,
Good to see you in Microsoft Community.
A similar phenomenon does occur after changing the authentication method of a Microsoft account. This is because the operation triggers the account security protection mechanism.
If you can currently log into the system normally, you can try the following steps:
- After changing your account security information, you may need to re-verify your identity in Windows Settings, make sure there are no words like "Your account need verify" in the Account section of Windows Settings, if there is, click on it and follow the prompts.
- Forget and reset: In Windows Settings, click “I forgot my PIN”****and follow the directions to verify your account with password and select a new PIN.
- You can follow the steps below to clean up Windows Hello related configuration information. Please run Command Prompt as an administrator ("Win" logo key + "Q", enter "cmd", select "Run as administrator"), and enter the following commands one by one.
net stop WbioSrvc cd C:\Windows\System32\WinBioDatabase ren *.DAT *.DAT.BAK net start WbioSrvc
If anything is unclear, please do not hesitate to let me know.
