I made code for signing in users and storing data about them. Everything is fully encrypted and secure. It is meant to be imported into other code. I'm looking for ways to improve it and to fix any bugs.

import pickle

import base64



class user():

    def __init__(self, username, password, user_data):

        self.username = username

        self.password = password

        self.user_data = user_data



def get_user():

    try:

        user_saves = open("users", 'rb')

        users = dict(pickle.load(user_saves))

        user_saves.close

        name, password, users = sign_in(users)

    except:

        name, password, users = new_user(True)



    name = base64.b64decode(name.decode('utf-8'))

    password = base64.b64decode(password.decode('utf-8'))

    return name, password, users



def new_user(is_first = False, users=None):

    print('Creating account... ')

    if users != None:

        loop = True

        while loop:

            name = input('What is your username: ')

            name = base64.b64encode(name.encode('utf-8'))

            if name in users: 

                print('Already taken.') 

            else: 

                loop = False

                password = input('What is your password: ')

                password = base64.b64encode(password.encode('utf-8'))

    else:

        name = input('What is your username: ')

        name = base64.b64encode(name.encode('utf-8'))

        password = input('What is your password: ')

        password = base64.b64encode(password.encode('utf-8'))

    if is_first == True:

        user = {name:password}

        user_saves = open("users", 'wb')

        pickle.dump(user, user_saves)

        add_user_data('', password, True)

        return name, password, user

    else:

        add_user_data('', password)

        users.update({name:password})

        user_saves = open("users", 'wb')

        pickle.dump(users, user_saves)

        return name, password, users

    user_saves.close



def sign_in(users):

    nsi = True #not signed in

    while nsi == True:

        username = input('What is your username: ')

        username = base64.b64encode(username.encode('utf-8'))

        if username in users:

            password = input('What is your password: ')

            password = base64.b64encode(password.encode('utf-8'))
