Use your subscriber's email address as their username
We recommend checking this setting so you can force a new subscriber’s username to be their email address during sign up for Leaky Paywall. It also simplifies registration forms since there is no 'username' to fill out.
1. In the WP admin, go to Leaky Paywall > Settings > General.
2. Check the box for " User Account Creation".
This will remove the username field during registration and use their email address to generate an account username.
