Sign-in
Use your passkey to sign in using [passkeys form
autofill](https://developers.google.com/identity/passkeys/use-cases#passkey-autofill-suggestions-in-form-fields).
If you haven't created a passkey yet, sign in with a username and
password if you haven't created a passkey yet. You can use a random
username, no account creation is needed. Once you are signed in, create
a new passkey and sign out to come back here.
### Sign in with a passkey
To sign in, place your cursor on the username field. You'll notice the
autofill dialog contains your passkeys in addition to passwords. Select
the passkey you want to sign in with, and perform [user
verification](https://web.dev/articles/webauthn-user-verification) when
prompted.
To try [one-button sign-in
experience](https://developers.google.com/identity/passkeys/use-cases#sign-in-with-a-passkey-button),
press **Use a one-button sign-in instead** button.
