2FAinPython, An example for Two-Factor Authentication (2FA) in Python

totp.py, time-based One-time Password (TOTP) is a time-based OTP. The seed for TOTP is static, just like in HOTP, but the moving factor in a TOTP is time-based rather than counter-based.

hotp.py, each time the HOTP is requested and validated, the moving factor is incremented based on a counter.
