From its description, we believe SessionCreator could solve several of the problems we've encountered by letting us run a truly headless session, but password security is preventing us from being able to use it. The user account(s) running our tests have access to highly-regulated data and we simply cannot pass the authentication details it in the command line or store it in plain text in a file.
Please add support for encrypted passwords, re-using an existing session based on a key of some kind, or some other method so we do not have to have passwords visible in plain text.
