The problem

Hello, I'm using this script in order to get my calendar events:

from datetime import datetime, timedelta
 
api = PyiCloudService('my_apple_id', 'my_password')
if api.requires_2sa:
    import click
    print("Two-step authentication required. Your trusted devices are:")

    devices = api.trusted_devices
    for i, device in enumerate(devices):
        print(
            "  %s: %s" % (i, device.get('deviceName',
            "SMS to %s" % device.get('phoneNumber')))
        )

    device = click.prompt('Which device would you like to use?', default=0)
    device = devices[device]
    if not api.send_verification_code(device):
        print("Failed to send verification code")
        sys.exit(1)

    code = click.prompt('Please enter validation code')
    if not api.validate_verification_code(device, code):
        print("Failed to verify verification code")
        sys.exit(1)

start_date = datetime.now()
end_date = start_date + timedelta(hours=2)
events = api.calendar.events(from_dt = start_date, to_dt = end_date)

print(events)

1. I don't have an apple device, had one and with that id and password i'm working, so I'm using two step authentication in order to receive an SMS in my non apple phone.
2. I receive my SMS and I introduce the code number well but then it says me Failed to verify verification code.
3. When I run the script for the second time with the same apple'id and password it throws me the error logs attached in this description, not authenticated ( ref: Traceback/Error logs)
4. Then I realized that my account is locked and api.requires_2sa is set to False, so I need to go to https://appleid.apple.com/ and change my apple id's password.
5. Changed my apple id's password and api.requires_2sa is set to True again, run the script and it says me Failed to verify verification code once again.

My question are:

1. do I need to have an apple device in order to do this and try with two step authentication? (I think two factor authentication is not working)
2. Why api.requires_2sa is set to True the first time and when you fail is set to False ?
