Feature Request - Allow to define a login is for internal/intranet/testing

I have a few passwords that I'd like Watchtower and other features to ignore as unsafe, they are either a common weak password because the system is just for internal QA testing (they are reinstalled fresh with a default password very often) or demoing an API with well-known credentials (e.g. Stripe). Or even set at the hardware (e.g. my modem provided by my ISP, I tried changing the default password only for it to be reset after a reboot, can't fix that outside buying my own modem or changing ISP)

Thank you
