ssh-keygen -t ed25519 -C "your_email@example.com"

• Press Enter to save to default path (~/.ssh/id_ed25519) or change it any path you want
• Optionally enter a passphrase for extra security

Step 3: Start the SSH Agent

eval "$(ssh-agent -s)"

Add your private key to the agent:

ssh-add ~/.ssh/id_ed25519

cat ~/.ssh/id_ed25519.pub
