What is the Difference between Abstraction and Encspsulation

Abstraction is showing only necessary things, but Encapsulation is hiding complexity. for example, if we have a user log in form then we need only user id and password and a function to put on login button this shows abstraction (only necessary things) but logic should be written in some other class...
