That's not my experience. The account details stay open for me.
For me the UX is not amazing, but ok. A bit better than LastPass, a bit worse than 1password.
https://recordit.co/QdK2FrRoYX I copy the password, go to paste it in and it loses the selected account:
https://recordit.co/jrvUFWCPkS Here, I go to add an account. I generate a new password and then I try to paste it into the text box to verify it meets the website's password rules. I then go back to hit save, confirming that it worked and it loses the entry.
Sooo frustrating.
I use Bitwarden myself and I only need the copy/paste button for stuff like email and WiFi passwords. If you're manually copying and pasting data, you're probably overlooking one of the many (sometimes not clearly indicated) features Bitwarden has.
Hope this helps!
I used (paid for across Windows/macOS/iOS) 1Password for years but switched to Bitwarden because AgileBits kept openly making progressively more hostile moves against customers like me, and weren’t remotely apologetic about it. I would strongly advise anyone considering use of their products against it. Capturing and controlling use is more important to them now than serving users.
I'm genuinely curious about some examples of these "hostile moves"?
Definitely consider it over the $5/month subscription to 1Password or if you need shared vaults.
