How to write a program that remembers the data entered earlier and uses it?

Question

Python

Briefly speaking. First, I will write the question in more detail, then I will go into "well, in general, how I think this should be done."
Suppose there is a simple if-elif program, which, depending on the entered password, displays some information by type

login = str(input("Введите логин: "))
password = str(input("Введите пароль: "))

if (login == 'TheAmmiR') and (password == 'mysecretpassword'):
    print("Рады вас приветствовать, администратор интернет-магазина \"Утюг\".")
elif (login == 'User') and (password == 'none'):
    print("Рады вас приветствовать в нашем интернет-магазине!")
else:
    print("Неправильно введенный логин или пароль.")

And now such a task. How to register, according to the principle of the same ...

login = str(input("Enter your login: "))
password = str(input("Enter your password: "))

..?
At the same time, it will be remembered, and it can be used in the authorization process.
In my opinion, you should create a text document in which logins and passwords will be stored in a certain format. But how then to use them in the program itself? Tell me, who knows, maybe there are still separate libraries or modules for these purposes?
