# Adding passkey MFA to your Keycloak login flow
> Learn how to add passkey MFA to your Keycloak login flow with Authsignal.
## Overview
In the [previous guide](/integrations/keycloak/keycloak-mfa), 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](/authentication-methods/passkey/prebuilt-ui).
## 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.

## Next steps
In the next guide, we will demonstrate how to set up passkey autofill.
This will allow users to use their passkeys by clicking on the username or password input fields.
