Threads, the eternal cycle, asyncio

I need to log in to multiple accounts at the same time, and I was advised to create a stream. How can I do this?

def startChecking(login, password):
    session = startSession()
    logIn(session, login, password)
    while True:
        lastData = findAll(session)
        time.sleep(5)
        lastChat = findAll(session)
        if lastData == lastChat:
            gg = 0
        else:
            print(f'{login}', lastChat['userSms'])

if __name__ == '__main__':
    # There will be a for loop that will take the login and password
    session = startSession()
    logIn(session, 'login', 'password')
    while True:
        lastData = findAll(session)
        time.sleep(5)
        lastChat = findAll(session)
        if lastData == lastChat:
            gg = 0
        else:
            print('login\nNew message:', lastChat['userSms'])

The code will be something like this:

if __name__ == '__main__':
    # There will be a for loop that will take the login and password
    allAcc = list(collectionFunPay.find())
    for i in range(0, len(allAcc)):
        print(allAcc[i]['login'], allAcc[i]['password'])
        loop = asyncio.new_event_loop()
        asyncio.set_event_loop(loop) # An eternal cycle that must be performed continuously
        loop.run_until_complete(startChecking(allAcc[i]['login'], allAcc[i]['password']))

But it doesn't work.
