Get data of user after login (but not with craft()->userSession->getUser())

Question

Can I directly get the data of the user that I just logged in with craft()->userSession->login($username, $password) ? (not from a method that uses the SESSION like craft()->userSession->getUser() though)

Answer 1

If you have the any identifying information about the user (user ID, email, username, UID), you can use one of the UsersService's methods:

craft()->users->getUserById()

craft()->users->getUserByUsernameOrEmail()

craft()->users->getUserByUid()

craft()->users->getUserByEmail()

They will each return a UserModel object to interact with.
