Set up a connection
Add the host
Section titled “Add the host”Name, Host, Port, Username. Save turns on the moment Name and Host both have text — everything else has a working default.
Pick how you sign in
Section titled “Pick how you sign in”A password, a key you generate on the phone, or a PEM you paste. The secret goes to the iOS Keychain; the connection record only holds a reference to it.
Check the fingerprint
Section titled “Check the fingerprint”The first handshake stops and shows the host key with the ssh-keygen line to compare it against. Trust, or Cancel.
