[keycloak-user] Client Registration performance

Hello Keycloak Users! We are planning on using the Client Registration flow for setting up clients on login. This is mainly to more clearly identify each individual device a user has logged in with. Are there anyone using this feature in production with a large number of clients? With our current stats, we would probably end up with a few million clients by the end of the year. 1. Will this scale well with the way Keycloak works? 2. If a user loses their device, how should a full revoke & logout be performed? 3. Is there an alternative approach to give each user more control over their device and session? Thanks, Eivind Larsen
