Seems like they have some version of it implemented:

> Q: I need an old password! Can I view the history of a password that I changed in Bitwarden?

> A: Yes! You can view the last 5 passwords for any Login Item. Open the item in question and select the “1” next to Password History near the bottom of the window.

Seems like only on passwords, but great that it does at least have it on passwords!

Wait, you mean password history? As in being able to see the old password once you generate a new one or otherwise update it? Because Bitwarden definitely has that.

Spun up a Vaultwarden docker and gave it a try. You are correct, it does have password history. That's great. It was probably there the whole time and I didn't notice when I evaluated last.

I see it doesn't have history anywhere else, such as secure notes, which 1password does have.

Might still be too tough to give up the extra types and tags, but having history on the passwords is a great step. Quite tempting indeed.

Password history is a feature on Bitwarden. In the browser extension, at the bottom of the entry, you'll have something like:

Updated: 18 May 2020, 16:22:44 Password updated: 18 May 2020, 16:22:44 Password history: 1

I stand corrected, thanks!
