Sign in with your passkey.
Works with iCloud Keychain, Google Password Manager, 1Password, Windows Hello or a hardware key. Scanning the QR code with a phone signs you in from a passkey saved on that phone.
Invited? Open the invitation link you were sent — it creates your account and its passkey in one step. Lost every passkey? Ask the owner for a recovery link.
Owner: the access token still works — open /?k=YOUR_TOKEN once on a device, then add a passkey from the Account tab so you never need the token again.
