Manage One Time Password (OTP) Settings

A one time password  (OTP) authenticator is a random series of characters that are sent to the mobile device number or email address of a user during authentication. For OTP to be available, a user must have a value set for at least one of the following system attributes:

  • Email
  • Mobile
  • Phone

Refer to Create and Manage User Attributes for more information on user attributes.

Modify OTP Authenticator Settings

  1. Click Main Menu > Administration > Policies > Authenticators. The Authenticators page appears.
  2. Select One Time Password from the left-side menu. The One Time Password settings page appears.
  3. From the OTP Type drop-down list, select one of the following:
    • Random—creates a random OTP
    • MemoPasscode™—creates an easier to remember OTP using a combination of letters and numbers
  4. In the OTP Length field, enter the number of characters to set as your OTP password. For example, if you enter 4, the OTP is always four characters in length.
  5. In the OTP Alphabet field, enter the characters that can appear in the OTP. You can enter specific letters, numbers, and special characters. For example, if you set it to a3# then the OTP will always include those characters.

    Note: Using VOICE over OTP with characters as the OTP values (instead of just numbers) is not easy for users to understand. Numeric characters only are recommended if using VOICE as the OTP delivery method.

  6. Enter the OTP Lifetime for the amount of time in seconds a user can use an OTP to authenticate after it is generated.

  7. Click the Confirm changes check box.
  8. Click Save.
