What is the difference between login and create account?
Summary of Login vs. Sign up. You log in to officially record your presence as a returning user, whereas sign up simply registers your intent to be present officially in the system. Sign up means to create an account as a new user so that you can log in later with your credentials.

One reason to have both is so that authentication can be done by the database server, but authorization can be scoped to the database.
