<p>Allow your WordPress users to log into other systems using their WordPress credentials!</p>
<p>This plugin will create a htusers file and create entries for the user roles that you specify. When a user logs into WordPress or updates their profile, their password is hashed and written to the file. The plugin handles password changes and resets automatically, so you can just set this up and forget about it!</p>


HTAuth Sync

Synchronize your Wordpress users with a htusers file for authentication outside of Wordpress
