A different way to sign in
A passkey uses a pair of cryptographic keys. The service keeps a public key, while your device or credential provider protects the private key. Signing in proves possession of that private key without sending it to the website.
Why the website matters
Credentials are associated with a particular service. That helps reduce the risk of entering a reusable secret on a lookalike page. Device authentication, such as a fingerprint or PIN, unlocks the credential locally; the website does not receive your fingerprint.
Plan for recovery
Before relying on passkeys, understand how your credential provider handles synchronization and recovery. Keep your recovery methods current and consider a second supported device or security key for important accounts. A secure sign-in method still needs a workable recovery plan.
Make the transition gradually
Check each service’s account settings for its supported authentication methods. Add a passkey, verify that you can use it, and review backup access before removing an existing method. Availability and recovery behavior vary between services.
