Yes. We let users login via email through Facebook Account Kit™.

Account Kit lets people quickly register for and login to your app by using just their phone number or email address — no password needed. It’s reliable, easy to use and gives you a choice about how you sign up for apps.

Account Kit is built for the mobile world, providing long-lived sessions, easy account management, and no passwords to remember.

When a person initiates a login with their email address, Account Kit sends a one-time link to the person’s email address.
