The OneTimePassword control allows creation of single use passwords.
The OneTimePassword control implements the HOTP algorithm defined in RFC 4226 (HMAC-Based One-Time Password) and the TOTP algorithm defined in RFC 6238 (Time-Based One-Time Password). These types of passwords are commonly used as a second factor of authentication in multi-factor authentication scenarios.
