Version 0.3.0 released with the fix for subfolder installs and a new option to customize the icon of the login button. Incidentally, the default icon was no longer visible since multiple betas because the name had not been updated for FontAwesome 5.
This update also brings Passport into FriendsOfFlarum.
The update is beta 12+ only because I updated the Zend namespaces to Laminas.
Updating from Flagrow
This extension replaces Flagrow Passport.
To upgrade from the old extension to the new one:
composer require fof/passport
Composer should let you know that flagrow/passport
has been automatically removed.
Enable the new extension in the admin panel.
Your existing settings will be migrated to FoF Passport automatically.
You should be good to go! All URLs stay the same.
