I just double checked in both Google Authenticator and Authy, and everything works as expected.

The most likely explanation is that your computer has clock drift. Make sure to sync your clocks on your computer and phone using NTP, and try again.

Yes, my phone delay 10s than my computer. test in pyotp: the pyotp code is different from google authenticator completely; test in opt, the code is same of google authenticator,but expire 10 seconds faster than google authenticator.

My authenticator work well in github account, google account. I think maybe there is implementation fault in pyotp?
