User Registration and Login (plus SQRL)

It’s glaringly obvious to me that a Standard YII application has a login screen, but no user registration screen. Rather than reinvent the wheel, where can I find a secure, well-written user registration and management module? I’m still trying to find my way around the Yii site(s), so I would appreciate being pointed in the right direction.

For anyone who doesn’t know what SQRL is, please read the WikiPedia article. It uses crypto principles to create a secure login. If any of the user registration and management code already supports SQRL that would be a major bonus.

Have any of these login systems been audited by a security expert?

Check advanced project template, there is registration screen. SQLR is not supported (check packagist if there are any extensions).

Many thanks!
