Python One Time Password Library

PyOTP is a Python library for generating and verifying one-time passwords, supporting both Time-Based One-Time Passwords (TOTP) from RFC 6238 and HMAC-Based One-Time Passwords (HOTP) from RFC 4226. It is widely used to implement two-factor (2FA) or multi-factor (MFA) authentication in various systems, compatible with apps like Google Authenticator. The library is actively maintained, with its current version being 2.9.0, and follows a regular release cadence.
