+
+Some Social Sign-in Providers such as Google or GitHub show the Redirect URL as part of the sign-in process:

+
+By default, Ory Network uses a redirect URL that points to the Ory Network domain.
+
+:::caution
+
+Changing the `base_redirect_uri` will break previously existing and functional social sign-in connections.
+
+To fix a broken connection, choose the provider you want to fix from the Ory Console social sign-in configuration screen and copy
+the updated redirect URL which now points to your custom hostname. Use the value you copied to update the redirect URL
+configuration of the social sign-in provider.
+
+:::
+
+This makes it easy to get started with Social Sign-in. To adjust the redirect URL to your custom domain, you need to update the
+`base_redirect_uri`:
+
+```shell
+## List all available projects
+ory list projects
+
+## Remove the configuration entry
+ory patch identity-config <project-id> \
+  --add '/selfservice/methods/oidc/config/base_redirect_uri="https://ory.example.org"'
+```
