AuthenticationMethods publickey ReKeyLimit 1G 10m AllowAgentForwarding no
A few remarks:
- Disallowing root login doesn't bring any security advantages if you're only allowing secure AuthenticationMethods anyhow. It can even decrease overall security, because if forces you to use sudo, which could be replaces with a malicious (keylogging or command injecting) shell alias within the context of the unprivileged user account you're using sudo from.
- Compared to
AuthenticationMethods publickeyhas the advantage of being more easy to check during blackbox security scans, without even requiring a user account on the machine to be scanned. A potential downside is that it will also prevent some 2FA login methods like TOTP from working.
