EDIT: realized this was for desktop, so removed the original list of mostly android apps. Here's my go to desktop apps:
Lollypop - music player Invoiceninja - open source invoicing service Meld - file/folder comparison Librewolf - hardened Firefox Joplin - notes QEMU/Virt-Manager - virtualization for that one windows app you still need KeepassXC - password management Element-desktop - Matrix client Gparted - no fuss partition management Lutris - game launcher that works with epic games (among many others) PDFarranger - best PDF management I've found on Linux
Soundconverter - easy to use file converter Restic - backups Fdupes - duplicate file finder Freetube - privacy respecting YouTube client Paperless-ngx - very well built electronic document storage. Must be run as a server.
I'm on KDE 🥲 That Gnome app has been almost enough to get me to switch though. There's a few Gnome apps that KDE doesn't have a comparable parallel to.
I haven't heard of 2fas before, they seem pretty interesting. I'm inclined to keep my password and 2fa vaults out of the cloud (thus Aegis and Keepass) so I'm interested in how the browser extension syncs data with a phone. If it uses a shared network or ephemeral data transfers that would be pretty nice.
If you're already using keepassxc, you can import OTP codes and use that. That's what I do when my phone is not around to use aegis. It's not as pretty, but it works.
I have a few codes duplicated in my keepass vault for the services I log in to often on desktop. The autotype is super nice in those cases. Other than that I do generally prefer having a separation between password manager and 2fa data though. Probably only a theoretical safeguard in my case, but simple enough to keep in place for the time being.
