I have a question, like the button above the domain, can a button be provided for auto WordPress login so that a user can log in to their WordPress without a username and password?
example softaculous install WordPress auto login system
Here is the screenshot:
You can do that from the MainWP control panel. It runs in a dedicated WordPress installation. You could easily install an instance as a site on your HestiaCP server and add the WordPress sites you manage to it. Specific questions about MainWP will be best handled in their community forum.
