# Configuring number matching authentication

Number matching allows the user to authenticate by matching the number displayed on the user's accessing device with the corresponding number in PingID mobile app.

Configure number matching as an allowed authentication method in PingID policy, and optionally as an authentication action within a policy rule.

Learn more in [Policy and rule authentication methods](pid_policy_and_rule_authentication_methods.html).

Learn more about the user experience in [Authenticating using number matching](http://docs.pingidentity.com/pingid-user-guide/pid_mobile_app/pid_mobile_app_number_matching_auth.html) in the PingID User Guide.

* If **Mobile app biometrics** is set to **Require** in the **Configuration** tab, the user must authenticate successfully using biometrics and then authenticate using number matching. |
