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.
You can also just set it in the hosts file
Reading one of the bugs on it, that was the route someone else took
Edit: got it working with hosts. Thank you!
