Plugin has a serious vulnerability.

The EXIT button does not work.

After logging in you are no longer able to log out.

When you click EXIT, it just looks like you are logged out but when you click the google button to log in again, you have instant access without having to enter the password.

The only way is to clear the browser’s cache completely.

This is a serious failure.

If you log in to the equipment that is not yours, be sure to clear the cache after logging out, as the browser will still have your password saved.
