The recent evolution is great and I’ve been a happy KDE user for many years, but my oh my is NetworkManager bad. It’s not good on all systems that use it under the hood, but I find it especially unintuitive and so outdated. The applet thing is fine (still suffers from weird behaviour from NM’s core), but actual settings screen drives me crazy… The Bluetooth one should also receive some love, but it’s decent. NM needs serious revision.

This. And to add to what other commenters have said, by using Bitwarden and paying for their Premium plan (very cheap, just $10/year), even if you don’t use all their features, you’re supporting a good project. It’s critical infrastructure, I think the price is more than fair.
Either way, you should always make periodic backups from any cloud service you use, encrypted of course.
