I think its redundant and an incredibly bad idea to have my email, vpn, calendar, and cloud provider host my passwords. If I wanted a cloud based password manager, I'd use a standalone tool like Bitwarden. (imo, I realistically think protons implementation in probably just as secure for the average user.)
Either way, I think a password database is too important to store in the cloud, so I use KeePass.
My bad, v tired when I replied. That is an interesting feature the only similar solution I can think of is using something like Fossify Dialer (a fork of the now ad-ridden and proprietary Simple Dialer) and use T9 dialing. That could achieve a similar speed / memorization as a gesture.
You could definitely get good enough at T9 to at least call people without looking at the screen.
