motp

A Dart library for generating Mobile-OTP (mOTP) codes.

Mobile-OTP (mOTP) is a one-time password algorithm first introduced in 2003 for Java capable mobile devices like phones or PDAs. Unlike the newer and more well-known HMAC-Based One-Time Password (HOTP) and Time-Based One-Time Password (TOTP) algorithms, mOTP requires a user-provided PIN in addition to a counter and a secret to derive the one-time password.
