[keycloak-user] custom providers

Hi Keycloak users, I am new to keycloak. With my team we are using Red Hat Single Sign-On 7.0 with Keycloak 1.9.8. I need to customize this a little bit. We support diffrent languages and actually some message are not display us we want. For example message in Racaptcha is not in language as expected. I found example how to register Google Recaptcha and how to add validation of form elements on the page: *https://keycloak.gitbooks.io/server-developer-guide/content/topics/auth-spi.html <https://keycloak.gitbooks.io/server-developer-guide/content/topics/auth-s... So I suppose if I will register my own Recaptcha I will can specify message I want to display. As written I need to deploy my jar (j*ust copy it to the standalone/configuration/providers directory*) First, I didn't find *providers *directory in configuration so I created one where I copied my jar and I restarted my server. Then I tried to add my FormAction to the registration Flow but I don't see any diffrence in admin console. I mean I don't think my jar was deployed( I new to jboss) I found there also another way to deploy jar: *throw jar in Keycloak deploy directiry* but I don't understand what is meant by the "Keycloak deploy/ directory" mentioned in the documentation. Another change I want to do is: in reset password page add email validation. I found some example. *Keycloak is designed to cover most use-cases without requiring custom code, but we also want it to be customizable. To achive this **Keycloak has a number of Service Provider Interfaces (SPI) which you can implement your own providers for*. Could you please recommend one which I should implement for this goal. I will appreciate any help. Best regards, Patrycja
