Instead of overlaying its own UI on top of form fields, I'd like Bitwarden (or any other PW manager) to act as a provider for the underlying system's native fill service, usually the browser, or Android, or OSX. They will always work much better than any 3rd party app.
Is that possible, does that exist?
Just to clarify, you mean something like it is done in iOs?
I think they do that on Android but also have the accessibility based option.
