I wonder which SSH client you are using. There don't seem to be many open source options. ConnectBot, the one I've been using does not seem to work anymore on my new Pixel 6.

I use Termius. It can leverage the hardware-backed keystore in the secure element (StrongBox keymaster) to generate protected ECDSA keys that aren't managed by the app or the OS.

I wish StrongBox could support ed25519 keys but that's not the case at the moment.

I'm not aware of any FOSS alternative to Termius that does the same.

    I wonder if it's specifically an issue with Windows hosts. I have a bunch of Linux VM's and no issue using ConnectBot from my pixel 6.

      I'm a long time user of JuiceSSH, although it hasn't been updated in quite a while, still works fine for me.

      Wonderfall Termius looks very good but I really don't want to use proprietary software for ssh.

      fomijafi Ok, that's weird I wonder whats going on. But I don't think that it has anything to do with Windows. I have the problem with a Linux host.
