A PHP Example Defer to a 3rd party for email & validation Use the SlimPHP framework for quick bootstrapping Allow either password or password-less authentication
What just happened? Registered users can authenticate with their password Registered users can request a secure, one-time login link sent to their inbox The application doesn’t care which way the users authenticate
How does this benefit us? One less password for users to remember More flexible authentication schemes for existing users The middleware stack could be further extended to support TOTP/HOTP/ U2F/etc
