Termius is a cross-platform SSH client. It is more accessible than PuTTY for example on Windows and thus you can manage remote servers more efficiently.
You can use the tool at your discretion. However we do not encourage its ability to automatically synchronize SSH keys or passwords.
To connect to servers via SSH, you should first add your SSH key to Termius’ keychain under Preferences ยป Keychain. Just call it id_rsa and paste the private key contents (the contents of the ~/.ssh/id_rsa file). Do not save your passphrase as well.
