• ubuntu touch UI framework / suru: qt 5 based, so slightly outdated underpinnings, but still actively maintained https://docs.ubports.com/en/latest/humanguide/index.html
• flutter: developed by google as a cross platform framework, tied to the dart programming language. https://flutter.dev/
• Canonical has created custom widgets for flutter, if you don’t like material design: https://pub.dev/packages?q=ubuntu
• uno.platform: C# framework for cross platform apps. https://platform.uno/

You could also use dedicated hardware to store your keys. Any FIDO USB key will do. I have a Yubikey that cost me less than 30 bucks.

It’s really handy, because I frequently use someone else’s device for work. All I have to do is plug it in, press the button on the key and enter the master password for the passkey storage. It’s like having a password manager on a USB stick.

And they can be hardware based as well. I have a cheap Yubikey USB dongle, which works as a passkey vault as well. Completely OS independent.

I found pipx the easiest way to install and manage a current ytdlp installation

sudo apt install pipx
pipx ensurepath

pipx install yt-dlp

Yes I know, it’s an additional package manager, but it actually is a package manager and will therefore ensure the setup is correct
