Hi! Could you give short explain, why codes, generated by otplib.totp doesn't match with any test 2FA application (chrome extensions, Google Authenticator, other test sites)? It's only work when use otplib.authenticator

I dont know why but generated code by both otplib.authenticator and otplib.totp doesn't match with code from 2FA application

Hmm. Maybe problem in time difference between your application and another 2FA app. otplib.authenticator works for me. What 2FA application did you used? You can try to paste your secret to Google Authenticator (mobile app) and compare. It should works.
