Edit: I realize you are probably using bitwarden directly, in which case don’t you trust them to safeguard your data?
ps: if it’s just ssh keys, just store them as key value pairs? I haven’t kept ssh keys for a long time thanks to tailscale ssh…
Yes i use bitwarden directly, no self hosting. I do trust them keep my data safe (although i also trusted LastPass at some point, big mistake) but why not also keep a local copy, just in case. The type of data you store in bitwarden is worth the hassle and if Bitwarden Inc. ever gets into big trouble suddenly you'll be glad to have the backup.
