Function closure adds authentication to functions

#Simulation authentication but there is a problem because the user name and password need to be repeatedly entered and solved in the following essay (simulation session) 

def auth_func(func):
     def wrapped(*args,** kwargs):
        user_name = input( " Please enter your username " ).strip()    
        passwd = input( " Please enter your password " ).strip()
         if user_name == " sb "  and passwd == " 123 " : #Note that the username and password here are both strings, not numbers and must be quoted
            res = func(*args,** kwargs)
             return res #Pay attention to the position of return here 
         else :
             print ( " Username or password is incorrect " )
     return wrapped #Note that there are no parentheses here and it will not run wrapped
