How to combine users of different systems in yii2?

Question

Good afternoon, now I use yii as a microframework, and I have it as part of a larger system in which the authorization / authentication system is already implemented. The question is how to combine the authentication system of an external project and the current one on yii using the identity class + screw RBAC to it. those. it will be like an add-on over the current parent authorization system. I would also like to understand how the authentication mechanism works. those. at what point methods from this class are used https://github.com/yiisoft/yii2-app-basic/blob/mas...
