Medo.Otp

Simple implementation of second factor one-time password algorithms as per HOTP (RFC 4226) and TOTP (RFC 6238). These OTP codes are most known for their 6-digit variant used in two-factor setups.

Features

  • Counter-based one-time passwords
  • Time-based one-time passwords
  • Configurable time-step
  • Configurable number of digits

Example

Time-based:

using var totp = new TimeBasedOtp();
var code = totp.GetCode();

Counter-based:

using var hotp = new CounterBasedOtp();
hotp.Counter = 123;
var code = hotp.GetCode();
