    if option1 == "register":
        Access()
    if option1 == "login":
        login()
begin()

This is because your first conditional will always be True. For example, let's see how an example input would work:

>>> option1 = "unknown input"
>>> if option1 != "login" and "register": print("TRUE")
TRUE

# If we split the statement into pieces, we can see why
>>> option1 != "login"
True
# The part after the `and` isn't testing anything, and is always True!
>>> bool("register")
True
# Your `if` statement effectively tests option1 != "login"
>>> True and "register"
True

To fix this, you want to make sure that option1 isn't either of the strings. You probably want to clean up the input value a bit too, by stripping any whitespace.

option1 = input("Login or Register: ")
option1 = option1.strip()  # remove accidental whitespace from the ends

# The fixed `if` statement
if option1 != "login" and option1 != "register":
    begin()
