To remove PIN or password-based sign-in options in Windows 11, the supported path is:
- Open Settings > Accounts > Sign-in options.
- Under Additional settings, turn off For improved security, only allow Windows Hello sign-in for Microsoft accounts on this device.
- If the Remove option for PIN (Windows Hello) was unavailable before, reopen the Sign-in options page and check again.
- If a work or school account is connected, go to Settings > Accounts > Access work or school, disconnect that account if it is still listed, then restart the PC and try again.
Relevant behavior from Windows support content:
- The Only allow Windows Hello sign-in setting disables the use of passwords for a Microsoft account on that device.
- Sign-in options can vary based on device configuration.
- PIN, picture password, and security key options are managed from Settings > Accounts > Sign-in options.
