Password Managers Resources

Simple solution when a web browser doesn't integrate with 1Password? I use Chrome, Firefox and Safari most of the time. The little symbols used to always pop up whenever I landed on a login page. Now they rarely do, and I find myself more and more often having to go into the app, search for the login and copy and paste.

Are there any industry standards or recommended configurations of product selection, namely within Mac OS environments that use both Chrome and Safari browsers? More specifically and simply, is the Bitwarden macOS desktop designed and/or is it equipped enough to be used as the exclusive platform in such environments, or will the sometimes-clunky browser extensions always be necessary?

I'm looking to break down a tier list of different departments in our company to securely share specific group passwords with certain affiliated employees based on department and title, just feel a little limited in my options at the moment. Any best practices would be greatly appreciated!
