passwordless_activated

Name: Activate passwordless login Type: Yes/No Default: No

When enabled, users can enter their email on the manager login screen. They receive a one-time login link instead of entering a username and password. The link is valid for the period set in passwordless_expiration.

This requires working mail delivery. Passwordless login is handled in manager/controllers/default/security/login.class.php.

Security note: anyone who can read the user's mailbox can log in, so enable it only when email accounts are appropriately protected.
