Troubleshooting Guide

Windows passkey fixes that actually solve lockouts

Q: Do I need TPM for passkeys on Windows?

Modern Windows passkey flows benefit from secure hardware, and TPM-backed protection is strongly recommended.

Q: Why did passkeys stop after PIN reset?

PIN reset can break trust relationship with stored credentials. Re-enroll Hello and recreate affected passkeys.

Q: Should I disable passkeys in enterprise?

In most cases no. Enterprises typically deploy passkeys with policy controls instead of removing phishing-resistant authentication.

Windows passkey reliability depends on system-level sign-in options and browser compatibility. This page maps the exact sequence to restore stable login.

Quick fixes

Configure Windows Hello PIN and biometric unlock.
Install pending Windows updates and reboot once.
Confirm browser is up to date and not blocked by policy.
Keep a hardware security key as recovery backup.

System prerequisites first

Troubleshooting at the account level fails if Windows Hello is broken. Validate system sign-in stack first.

Then test in Edge and Chrome separately to isolate browser-specific issues.

Credential mismatch scenarios

After profile migration or device replacement, credential references may exist in provider account but not on local authenticator.

One controlled passkey re-registration solves most mismatch cases.

Enterprise edge cases

Managed devices can enforce restrictions on USB, WebAuthn, or profile sync that look like random failures.

Collect policy status before making repeated retries that could trigger account lockouts.
