Using authenticators

An authenticator is a security measure that protects a resource from unauthorized access. Authenticators require you to provide information (such as a password) or respond to an action (such as entering a one-time password). Once you successfully respond to the authentication request, you can access your protected resource.

You might be assigned multiple authenticators to allow you to sign in to Identity as a Service and your applications. For example, if you have been assigned a Google authenticator and an Entrust ST authenticator, you can log in to Identity as a Service using either of the authentication responses generated by those authenticators.

Note: Administrators set the authenticators that you can use to access applications. As a result, you might not see the option to add or use all the authenticators described in this User Help. Also, when you log in, you might see a message that tells you that you need to register an authenticator. The following sections provide instructions on how to use and register the different authenticators.

When you log in to Identity as a Service, you enter your User ID on the login page and then respond to the second-factor challenge. Sometimes you need to enter your IDaaS User ID and password and then respond to an authentication challenge.

Note: To use another second-factor authenticator, click the Alternative Authentication link on the second-factor Authentication page and select the Authenticator from the list available.
