    for line in file:
        name, password = line.split(',')
        if name == enter_name:
            logged_in = password == enter_password
            break
        else:
            attempts+=1
            print('WRONG USERNAME OR PASSWORD')
            enter_option=input('ENTER OPTIONS:\n A-RETRY\n B-NEW ACCOUNT\n')
            while enter_option=='A':
                enter_name=input('ENTER NAME: ')
                enter_password=input('ENTER PASSWORD: ')
                if name == enter_name:
                    logged_in = password == enter_password
                    break
                else:

When you read from file the line has newline char at the end. It stays with password. You need to strip it in order yo match entered password.

How do I do that, I don't understand what you mean

You iterate over rows in file (line #8). You split every row on comma to two separate values (name, password). Every line in file ends with newline character (otherwise there will be one long line). So every password you extract is in form mypassword\n. If you compare it to mypassword you will never get a match.
