Quick diagnosis
Recover sign-in when a PIN is rejected, unavailable, or needs recreation.
Symptoms
- PIN is unavailable
- Something happened appears
Likely causes
- Account verification
- Security-state change
- Damaged credential
Quick reversible checks
- Use Sign-in options and password
- Confirm internet for Microsoft account
Establish the scope
Distinguish a rejected PIN from a PIN option that is unavailable. Check whether password sign-in works for the same account and record the exact prompt. A working password gives a recovery route, but does not explain why this device rejected its PIN.
Apply the safer fix first
Use I forgot my PIN and complete identity verification. A PIN is device-specific; an online password change does not replace it.
Investigate the cause
After password sign-in, recreate the PIN under Sign-in options if allowed. Never clear the TPM without understanding BitLocker impact.
Protect the recovery path
Use only the account-owner verification process. Do not clear the TPM, delete credential folders, or change encryption settings to bypass a sign-in failure.
Verification
- After a permitted PIN reset, lock the PC and sign in with the new PIN.
- Confirm the original account and files load, and retain the working password as an alternate sign-in method.
When to stop
Do not continue with broader resets when verification fails, the device is managed, or BitLocker information is uncertain. Preserve the observations already collected and use the device maker, network administrator, Microsoft support, a qualified repair technician, or data-recovery help according to the evidence.
Review the safe troubleshooting workflow before any broader recovery step.
