ssh-keygen -t ed25519 -b 256

(e g save as /home/user/ ssh/fedora_vps) then upload the public key with

ssh-copy-id -i ~/.ssh/fedora_vps.pub user@ip

Edit /etc/ssh/sshd_config with

nano /etc/ssh/sshd_config

setting PasswordAuthentication no and PubkeyAuthentication yes Restart SSH with

systemctl restart sshd

and test with

ssh -i ~/.ssh/fedora_vps user@ip

—expect no password prompt Open port 22 with

firewall-cmd --add-service=ssh --permanent
