OneTimePassword Component

Properties Methods Events Configuration Settings Errors

The OneTimePassword component allows creation of single use passwords.

Syntax

TipcOneTimePassword

Remarks

The OneTimePassword component 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.

To begin decide which algorithm you wish to use and set PasswordAlgorithm. Specify the shared secret in the Secret property.

Next, depending on the algorithm chosen you may set Counter (HOTP) or TimeStep (TOTP). If these properties are not set, the component will use a default value.

To create the password call CreatePassword. The Password property will be populated with the new password.

To validate a password set the Password property and call ValidatePassword. The method will return True or False to indicate success or failure.
