What’s the difference in web applications? In short, please.

I see the abbreviation "auth" a lot. Does it stand for auth-entication or auth-orization? Or both?

    Authentication is the process of ascertaining that somebody really is who they claim to be.

    Authorization refers to rules that determine who is allowed to do what. E.g. Adam may be authorized to create and delete databases,
    while Usama is only authorised to read.

    The two concepts are completely orthogonal and independent, but both are central to security design, and the failure to get either one correct opens up the avenue to compromise.

    In terms of web apps, very crudely speaking, authentication is when you check login credentials to see if you recognize a user as logged in, and authorization is when you look up in your access control whether you allow the user to view, edit, delete or create content.
