BitWarden is my password manager of choice, I use it a lot. But one thing I find frustrating and honestly, nonsensical, is why it doesn’t support ports out of the box? I have a bunch of services on different ports and would hope BitWarden would recognise that, but it doesn’t? It’s not a huge thing as I can always search, but it’s one of those little niggly things.
In addition to setting the host uri detection, you could put all your services behind a reverse proxy. Bitwarden would then easily detect the subdomain.
Reading one of the bugs on it, that was the route someone else took
Edit: got it working with hosts. Thank you!
