1. 1
   Username and invitation

   Unique and permanent: the username names your passkey on your device.

   Username

   Invitation code

   A code comes from the site's owner: one code admits one registration and lives a limited time.

2. 2
   Passkey

   Face ID, Touch ID, a PIN or a security key. The server keeps only the public key.

   The passkey lives in your device's keychain. No recovery exists: if you lose every device holding it, the account cannot be recovered; ask the site's owner to remove it and register again.
