This page describes how to configure the CA Mobile OTP (OATH-Compliant) settings in CA Strong Authentication.
Configuring CA Mobile OTP (OATH-Compliant) Issuance Profile
A CA Mobile OTP-OATH profile can be used to specify the following attributes for CA Mobile OTPs that are complaint with OATH standards.
  • Length
    : The length of the CA Mobile OTP
  • Validity period
    : The period for which a CA Mobile OTP is valid.
By configuring a CA Mobile OTP-OATH profile and assigning it to one or more organizations, you can control the characteristics of CA Mobile OTP credentials that are issued their users. Use the CA Mobile OTP Profiles page to create CA Mobile OTP credential profiles.
Follow these steps:
  1. Click the Services and Server Configurations tab on the main menu.
  2. Verify that the CA Strong Authentication tab in the submenu is active.
  3. Under the CA Mobile OTP-OATH section, click the Issuance link to display the CA Mobile OTP-OATH Profiles page.
  4. Edit the fields in the Profile Configurations section, as required.
    • Create
      To create a new profile:
      • Select the Create option.
      • Specify the Configuration Name of the new profile in the field that appears.
    • Update
      To update an existing profile, select the profile to update from the Select Configuration list that appears.
    • Copy Configuration
      Enable this option if you want to create the profile by copying the configurations from an existing profile.
      Note: 
      You can also copy from configurations that belong to other organizations that you have scope on.
    • Available Configurations
      Select the profile from which the configurations are copied.
    • Token Type
      Select the type of CA Mobile OTP that must be created for the user. HOTP represents counter-based tokens and TOTP represents time-based tokens.
    • Length
      Set the length of a CA Mobile OTP.
      The minimum length can be six (the default) and the maximum length can be eight characters.
    • Time Step
      The time interval, in seconds, during which the OTP generated by the client is the same as the OTP generated by the server. A larger time step allows the two OTPs to match for a longer period. In other words, a larger time step can accommodate a longer delay in receipt of the OTP from the client.
      You can enter any value from 1 to 300. The default is 30.
      Note: 
      This option is applicable only for OTP-based CA Mobile OTPs.
    • Logo URL
      Enter the URL that contains the logo to display on your client device which uses CA Mobile OTP for authenticating to CA Strong Authentication-protected applications.
    • Display Name
      Enter the name that is used to display the CA Mobile OTP on the client device. You can either enter a fixed string or pass the following user variables as $$(<variable>)$$:
      • user name (userName)
      • organization name (orgName)
      • credential custom attributes
      • user custom attributes
    • Validity Start Date
      Set the date from when the issued CA Mobile OTP credential is valid.
      The validity can start from either the date when this credential is created or you can specify a custom date.

Configuring CA Mobile OTP (OATH-Compliant) Authentication Policy
A CA Mobile OTP-OATH policy can be used to specify the following authentication-related attributes for CA Mobile OTPs that are OATH-compliant:
  • User status
    : The status of the user, which can be active or inactive.
    If the user status check is enabled, then the authentication for users in inactive state results in failure.
  • Lockout criteria
    : The number of failed attempts after which the user credential is locked.
  • Unlocking criteria:
     The time period after which a locked credential can be used again.
Follow these steps:
  1. Click the Services and Server Configurations tab on the main menu.
  2. Verify that the CA Strong Authentication tab in the submenu is active.
  3. Under the CA Mobile OTP-OATH section, click the Authentication link to display the CA Mobile OTP-OATH Authentication Policy page.

      Note
      : You can also copy from configurations that belong to other organizations that you have scope on.
    • Available Configurations
      Select the policy from which the configurations are copied.
    • Authentication Look Ahead Count 
      Enter the number of times the CA Mobile OTP counter on the CA Strong Authentication Server is increased to verify the CA Mobile OTP entered by the user. The CA Mobile OTP entered by the user is compared with all the CA Mobile OTPs that are generated from current count - Authentication Look Back Count to current count + Authentication Look Ahead Count on the server, and if the CA Mobile OTP entered by the user matches, then the user is authenticated.
      Note
      : If the client and server CA Mobile OTP matches, then that count is set as the current count on the server.
    • Authentication Look Back Count
      Enter the number of times the CA Mobile OTP counter on the CA Strong Authentication Server is decreased to verify the CA Mobile OTP entered by the user.
      The CA Mobile OTP entered by the user is compared with all the CA Mobile OTPs that are generated from current count - Authentication Look Back Count to current count + Authentication Look Ahead Count on the server, and if the CA Mobile OTP entered by the user matches, then the user is authenticated.
      Note
      : If the client and server CA Mobile OTP matches, then that count is set as the current count on the server.
    • Synchronization Look Ahead Count 
      Enter the number of times the CA Mobile OTP counter on the CA Strong Authentication Server is increased to synchronize with the CA Mobile OTP counter on the client device.
      To synchronize the client and the server CA Mobile OTPs, the user has to provide two consecutive CA Mobile OTPs and if these CA Mobile OTPs match with the consecutive server CA Mobile OTPs in the lookup range (count - Synchronization Look Back Count to current count + Synchronization Look Ahead Count), then the server counter is synchronized with the count corresponding to the second CA Mobile OTP entered by the user.
    • Synchronization Look Back Count 
      Enter the number of times the CA Mobile OTP counter on the CA Strong Authentication Server is decreased to synchronize with the CA Mobile OTP counter on the client device.
      To synchronize the client and the server CA Mobile OTPs, the user has to provide two consecutive CA Mobile OTPs and if these CA Mobile OTPs match with the consecutive server CA Mobile OTPs in the lookup range (count - Synchronization Look Back Count to current count + Synchronization Look Ahead Count), then the server counter is synchronized with the count corresponding to the second CA Mobile OTP entered by the user.
    • Lockout Credential After
      Specify the number of failed attempts after which the CA Mobile OTP is locked.
    • Check User Status Before Authentication 
      Select this option if you want to verify whether the user status is active, before authenticating them.

      Specify the time period in seconds after which a locked credential can be used again for authentication.
    • Alternate Processing Options
      The 
      Advanced Authentication
       Server acts as a proxy and passes the authentication requests to other authentication servers, which are based on the following conditions:
      • User Not Found: If the user trying to authenticate is not present in the 
        Advanced Authentication
         database, then the request is passed to the other server.
      • Credential Not Found: If the credential with which the user is trying to authenticate is not present in the 
        Advanced Authentication
         database, then the request is passed to the other server.
