Most people use an extension on web and an app that uses the system autofil functionality on mobile (at least on android, I’ve not used iOS for a long time)

You don’t have to open anything, or type anything other than a password. On mobile you just use your fingerprint, don’t have to type anything at all.

If you’re taking about initial setup that’s also gonna be a lot more complicated for an average user than bitwarden.

A command line tool is not even remotely a comparable user experience. It may work wonderfully for you, and I’m glad it does, but it’s pretty out of touch to suggest that it’d be a good fit for most people
