While searching for SSH client for my Nexus 5X, I discovered 'Termux'. I was expecting another SSH app. But, what I got was Linux terminal as the first screen. Interesting! I had to generate keys (ssh-keygen), and copy them to my computer (tar -cf - id_rsa id_rsa.pub | nc 1.2.3.4 1234). Which SSH client do you use on your phone? -- William
