A passkey can replace the password you type when signing in to a supported account. The change is worth understanding before you accept a setup prompt, especially if several people use the same computer.
What changes? A password is a secret you enter. A passkey uses a cryptographic key pair, with the credential managed by your device or passkey provider. You typically approve its use with a fingerprint, face unlock or device PIN. The FIDO Alliance describes passkeys as phishing-resistant: they are designed to protect sign-in against fake login sites.
Does your fingerprint go to the website? Google says biometric data used to unlock a passkey stays on your device and is not shared with Google. Your fingerprint is an unlocking method, not a new password to send.
Will it work on another device? That depends on how the passkey is stored. Some can sync through a provider; others are tied to particular hardware. Check where yours will be saved and how you would sign in after losing or replacing that device.
Should you delete your password immediately? Do not assume setup removes it. Google’s account guidance says adding a passkey does not remove existing authentication or recovery factors, and a password can remain available.
A sensible first step: choose one supported account and read its official setup and recovery instructions. Create a passkey only on a personal device you control. Google warns that someone who can unlock a device holding your passkey may be able to access your account. Keep the screen lock private.
