Adding passkey MFA to your Keycloak login flow

​

Overview

In the previous guide, we demonstrated how to add an MFA step to your Keycloak login flow using Authsignal. In this guide, we will add passkey MFA to your Keycloak login flow using Authsignal’s pre-built UI.

​

Configuration

Set up passkeys by following the steps in Authsignal’s pre-built UI + passkeys configuration guide.

​

Testing the flow

The next time users log in and complete an MFA challenge, they will then be prompted to add a passkey. Once users have added a passkey, they will be prompted to use passkeys for MFA by default.
