-      You must define the (`{{ item.username }}`) and (`{{ item.password }}`) configuration settings to properly configure an account using Jitsi's internal authentication.
+      Each Jitsi user in `matrix_jitsi_prosody_auth_internal_accounts` needs to have a non-empty `username`/`password`.
 
       Please ensure you have defined at least one user and password when using internal authentication.
       
       If you're setting up Jitsi for the first time, you may have missed a step.
       Refer to our setup instructions (docs/configuring-playbook-jitsi.md).

-      If you had previously setup Jitsi successfully and are only now facing this error,
-      it means that your installation is most likely using default passwords previously defined by the playbook.
-      These defaults are insecure. Jitsi should be rebuilt with secure values.
-      Refer to the "Rebuilding your Jitsi installation" section in our setup instructions (docs/configuring-playbook-jitsi.md).
