Hi @warmwhisky,
I’m, sorry to hear you are having issues with this. I’ll try and shed some light on it.
This feature was built to prompt to save, on a locked vault, because especially new users would forget about unlocking their vault beforehand. Which also led to a lot of false reports found on: Bitwarden does not prompt to save or update credentials · Issue #1620 · bitwarden/browser · GitHub
If the vault is locked all of your data is encrypted and there is no way for Bitwarden to know which sites you might have credentials saved for.
I’m assuming the reason you are seeing these save prompts are: A locked vault and manually entering your credentials to a website.
If you’d for example use the shortcut (Cmd/Ctrl+Shift+L) or the context-menu to trigger auto-fill it will prompt you to log-in on a separate tab, unlock the vault and auto-fill.
As the vault is now unlocked and the credentials match an existing entry, no save-prompt is shown.
There is currently no setting to disable this functionality only for a locked vault. The setting mentioned earlier in this thread only disables all save or change password prompts.
If you are not entering your credentials manually and there is another reason for the prompt showing, then please detail all steps on the Github issue mentioned by @not
I hope this clears up some of the confusion.
Kind regards,
Daniel
