Allowing passing the password directly is convenient for developers, for Docker image, for provisioning tools, etc.. So we're not going to remove that it's required, but I do appreciate that if not used correctly it's a potential security risk. The worst case scenario here is really that someone gets an admins favorite password, as someone that has access to getting the bash history of that particular user will also be able to run the add-user script themselves. So if the admin wants to print his favorite password in clear text in the bash history we should not stop him. <br></div>

<div>It's not our responsibility to clear the bash history, so we should not do that either. <br></div>

<div>At the very least, we should print a warning message to let the administrator know he has done something that is potentially insecure.<br></div>

<div>So I'm saying we should either disallow setting on the command line or somehow disable saving to the log. We shouldn't rely on an administrator to do the right thing.<br></div>

<div>If this can't fix the issue, is also possible to disable bash_history temporarily. But I wouldn't take this route, because this is pretty much system administration responsibility.<br></div>

<div> </div>
<div>On Windows, this really isn't a problem because command history is not saved. After a CMD session ends, the history is lost (unless you install some third-party tool).<br></div>
<div> </div>
<div>Perhaps there is a way to temporarily disable logging of command history in the add-user-keycloak.sh?<br></div>

<div>The situation is even more complicated with Docker, since running the<br></div>
<div>script to change the Wildfly admin password requires restarting the<br></div>
<div>server, which shuts down the container. If you have an autoscaling<br></div>
<div>group, the container that gets brought up is not the container where you<br></div>
<div>changed the password, but instead the original container. This seems to<br></div>
<div>mean that the only way to have Keycloak run in Dockers in an autoscaling<br></div>
<div>group is to bake the admin passwords into the Docker image beforehand.<br></div>
<div>This isn't ideal; less so if the only way to add those passwords during<br></div>
<div>build time is to run the shell script that exposes the password on the<br></div>
<div>command line.<br></div>
</blockquote><div> </div>
<div>You need to set the password once for your database. This can be done prior to accessing the admin console the first time. Take a look at <a defang_moz-do-not-send="true" href="https://github.com/jboss-dockerfiles/keycloak/blob/master/server/README.md" target="_blank">https://github.com/jboss-dockerfiles/keycloak/blob/master/server/README.md</a>, you can use docker exec to do this.<br></div>
