Looks like I picked the right year to switch to Linux on my primary pc.

I self host Bitwarden and it’s free to self host. You only have to pay for a license if you need multiple users or want to use their cloud services, I believe. My instance is 100% self hosted and completely isolated from the internet, and it works fine.

I self host it because I self host everything, but for credential managers I would never trust any 3rd party closed source utility or cloud service. Before I used a password manager I tracked them all manually with a text file and a TrueCrypt volume. I think giving unrelated credentials to 3rd parties is asking for trouble - they definitely don’t care as much about them as you do!

If you’re going to self host any credential manager, make sure you have an appropriate backup strategy, and make sure you have at least one client synced regularly so that you can still access passwords if the server itself dies for some reason.
