SSH keys

Create an Ed25519, ECDSA or RSA SSH key in Wardterm, or import one you have, add its public key to a server and sign in without a password.

Create a key

  1. Open Keys. On Mac choose New Key, on iPhone and iPad choose +.
  2. Choose Generate key.
  3. Give it a Name and choose the type: Ed25519, the default, or ECDSA or RSA for servers that need them.
  4. Add a passphrase if you like.
  5. Choose Generate.

The same key with OpenSSH:

ssh-keygen -t ed25519 -C "deploy@laptop"

Import a key

  1. In Keys, choose Add existing key.
  2. Paste the private key, or choose Load from file. OpenSSH, PEM and .ppk keys all work.
  3. If the key has a passphrase, enter it.
  4. If you sign in with an SSH certificate, paste it in Certificate.

On Mac, Import keys… in Settings, SSH Agent brings in all the private keys in ~/.ssh at once.

If the app says Convert this key with ssh-keygen -p, convert the key with OpenSSH, then import it again:

ssh-keygen -p -f ~/.ssh/id_rsa

Add the key to a server

  1. Open the key and choose Add to a server.
  2. Choose the server. The app signs in with its current login and adds the public key to ~/.ssh/authorized_keys, creating the folder and the file with the right permissions if they are missing.
  3. When it says Key added, choose Use to sign in so that the server signs in with the key from now on.

The same with OpenSSH:

ssh-copy-id -i ~/.ssh/id_ed25519.pub deploy@203.0.113.10

To use a key on a server by hand, choose it in the server's Key field.

Copy or show a key

  • Copy public key puts the public key on the clipboard, to paste it where a service asks for it.
  • Show private key shows the private key.
  • The menu of a key has Copy public key, Edit, Share with team and Delete.

Keep a key on one device

Turn on This device only in a key to keep its private part on this device. It is not synced: your other devices get only the public key. For a key that can never leave the device, see Keys on this device, and for a YubiKey, Security keys.

Saved logins

A login is a user with a password or a key, saved under a name and used by many servers. Change it once and every server that uses it gets the change.

  1. In Keys, choose New login.
  2. Fill in the user and the password or key.
  3. In each server, choose the login in the Key field.

In Settings, Security, under Checks: Find repeated sign-ins finds servers where the same user and password are typed in each, and saves them as one login. Check security of all servers checks every server and shows a summary.
