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 phone number, the user can select either SMS or WhatsApp and Account Kit sends a confirmation code to that number for validation, or verifies the number directly.
