[keycloak-user] Login via Magic URL

Hi All, I'm trying to lower the barrier for users by sending them a 'magic' link to login without a password into a mobile app. The general flow would be as following: 1. backend requests 'single use token' from Keycloak via API 2. backend sends email with this token to user via e.g. email as part of a magic link 3. user opens the link on a mobile device 4. the uri scheme/domain is registered in the mobile OS for a specific app, app gets opened 5. mobile app exchanges 'single use token' for a refresh token 6. user is logged in :) As I understand there is no such flow available in Keycloak. Looking at the SPI interfaces one might be able to implement something like this by adding custom API endpoints and ActionTokenHandler. Since I doubt I'm the first one to explore magic deep links with Keycloak, did anybody already implement that? Did I miss a feature that already exists? Is there an easier way to achieve this with Keycloak? Cheers, Thomas
