Issue description

It would be really great to be able to use Redis instances that have passwords activated. Typically this would be another environment variable that we could use like REDIS_PASSWORD.

Why is this feature important?

It would enhance the security of the stack beeing used to run sure and as we are in a pretty sensitive area with money, i think this would make sense.
