key authentication

Easy Rhino · Jul 26, 2016

Quick poll! I finally got around to securing my remote VM by disabling password authentication and using key authentication only for SSH. Curious if others do the same.

Over my head

No, but I should be! :toast:

I actually recently switched to key authentication myself.

I'm using a mix of RSA keys (for the first handshake) + an OTP code as a second authentication factor.

I set openssh to listen on a non-standard port, with a restricted set of IPs allowed to knock at the door.

All this in raspbian, on an old B+ running 24/7

Key authentication is the recommended method for security, reject all password logins

If you lose the key use physical or remote console (IPMI)
