Once a site has your passkey, signing in is a confirmation rather than a typed secret.
The sign-in sheet: iOS confirms the passkey saved in DroidPass before anything is sent. Again the site is a local test page.
Why this matters
Passkeys let you sign in to websites and apps without a password. DroidPass keeps them encrypted with a Secret Key that never leaves your devices.
Steps
Open the site and tap its sign-in field.
Choose your DroidPass passkey from the list your device offers.
Confirm with Face ID, your fingerprint or your Master PIN.
If it does not work
Open DroidPass and unlock your vault once. AutoFill has nothing to offer while the vault is locked.
Passkeys were set up on another device. Enter the Secret Key from your Emergency Kit, or scan the code shown in DroidPass on that device.
Good to know
Passkeys cannot be phished: the key only works on the site it was made for.
If nothing is offered, open DroidPass and unlock it once β a locked vault has nothing to offer.
To try one without touching a real account, passkeys.io is a public demo by Hanko. It asks for an email address and a made-up one is fine β but that passkey is then the only way back into that demo account.
