Yii to use Wordpress Logins

Is it possible to allow users created in my Wordpress database to be used with Yii?

I have a website that uses Yii for a plugin. This plugin has a separate login system, but I would like it to allow users created within Wordpress to work with Yii. Any thoughts on how this can be accomplished. I have searched for a few hours and haven’t come up with much.

Yes, it is possible.

You will have to implement UserIdentity to match login/password entered by user with wordpress database. To do this you will probably need to know password hashing method used in wordpress. But knowing the hash function - everything should be easy.
