unable to log in

I try to log in dyson account like below code.
dyson_account = DysonAccount("XXX@hotmail.com","123456","US")
logged = dyson_account.login()
if not logged:
print('Unable to login to Dyson account')
exit(1)
but it shows unable to login to Dyson account.
Is the account and password the same as APP Dyson link?
or anything wrong?
Thanks
