Is it based on ActivityPub? I don't really know much about it other than Jack Dorsey is involved.

I've had a lot of luck with banking apps on GrapheneOS. Worth a try if you haven't already.

Then stand up your own server and govern it as you please.

its not a huge issue on KeePassXC because I keep a yubikey nano plugged into my laptop, but for my phone, I haven't been able to make this work reliably with KeePassDX. I'll have to give it another go.

Ok great, coming from Reddit, I was unaware I could edit the post title. thanks

I like the look of KeePassDX but I was bothered by the fact that I have to use the yubikey every single time to unlock the database, unlike keepass2android which allows me to store the yubikey credential with biometric lock until the phone restarts. Keepass2android is not as nice of an app but that feature was really required for me.

It does require some configuration within yubikey manager. I did not find it straightforward but once set up its really reliable.

Would self hosting be possible (and fairly reliable) on a SBC?

So I can sign up for beeper and connect through Element or another Matrix app of my choosing?

no, you're wrong. This organization is basically still experimenting, and they have come a long way over the years. There are also efforts to trap plastics at mouths of rivers to try and slow down polluting the ocean. There is hope yet.

How does NixOS compare to SteamOS on the Deck? Does it work just as smooth? Also, is EMUDeck compatible with NixOS?

Is the fact that you're using a bridge at all apparent to your WhatsApp friends? Or is nothing different as far as they are concerned? Also, does Element have a setting to prevent pictures and video from being automatically downloaded over cellular data?
