Используйте json.dumps для добавления к файлу json следующим образом:

import json


def log_in():
    while True:
        login1 = input('Please enter your existing username: ')
        login2 = input('Please enter your existing password: ')

        if login1 != "" and login2 != "":
            break

    with open("data.json") as f: 
        data = json.load(f) # <-- Fixed the bug, again

    if data[login1] == login2:
        # User sucessfully logged in
    else:
        print('Access Denied')

def sign_up():
    username = input('Please enter your new Username: ')
    password = input('Please enter your new Password: ')
    user = {
        "name": username,
        "password": password
    }

    with open('data.json') as f:
        data = json.load(f)

    data.update(user)

    with open('data.json', 'w') as f:
        json.dump(data, f)

    print('Thank you for submitting your new account.')
    log_in()

message = 'If you have an account on this repl'
message += 'please press 1 if you do not please press 2:'

while True:
    sign_or_log = input(message)
    if sign_or_log == "1":
        log_in()
        break
    if sign_or_log == "2":
        sign_up()
        break
