For my devices who are not running DietPi I’m using this tutorial to enable Passwordless SSH Access from my Mac … but here it seams to not working … maybe I’m forgetting something or a step?
https://www.raspberrypi.com/documentation/computers/remote-access.html#passwordless-ssh-access
The guide you linked specific to OpenSSH. But on DietPi we use Dropbear SSH server. There your guide might not fit.
You could have a look to following guide https://openwrt.org/docs/guide-user/security/dropbear.public-key.auth
Or change SSH server preference from Dropbear to OpenSSH using dietpi-software
Yeah, keys in dropbear are stored in /etc/dropbear/authorized_keys in contrast to ~/.ssh/authorized_keys in openssh
trying to have it working with dropbear for knowledge
I can see the authorized_keys file populated with my key … but it’s still prompting for my password when I ssh to it
not sure which SSH client you are using but in Putty you need to configure the key to be used https://openwrt.org/docs/guide-quick-start/sshadministration#putty
I’m using terminal from macOS
not sure why but the file must be on both location so I did cp /etc/dropbear/authorized_keys ~/.ssh/authorized_keys and it fixed it
