I'm using an SFTP server app on my Android phone (RedMi 3S); it's a typical Android app, not something requiring root or run as an ARM binary from the command-line). This server app lets me define some username+password combinations for connecting. So far - so good.
Now, I want to use some public keys to allow password-less connection from certain people/hosts. But - where should I put them? What's the equivalent of the faux-user's
I realize I can just put them anywhere and it'll work, I'm asking what's the customary location for this kind of data.
