Command: ssh-copy-id

Install your public SSH key on the server.

Use ssh-copy-id followed by the personal SSH address printed during registration. Do not target new.

What It Does

ssh-copy-id appends your public key to the remote account’s ~/.ssh/authorized_keys. After that, SSH can prove your identity with the private key instead of only a password.

Expected Flow

1. It connects to the server.
2. It may ask for your account password one last time.
3. It installs the public key.
4. You disconnect, reconnect with that same personal SSH address, and run whoami.

Common Failures

• Target is new@...: wrong account. Use the personal SSH address printed during registration.
• No identities found: reuse a safe existing key or generate one with ssh-keygen only when needed.
• Permission denied: check username and password, then confirm the account exists.
• Still asks for password after install: use verbose mode with your personal SSH address and inspect which key files SSH tries.

Docs Pointers

• Run man ssh-copy-id.
• Read SSH Keys.
