How to connect via SSH with an SSH Key

In this article, you will learn how to establish an SSH connection with an SSH Key using Termius. Discover how to add an existing SSH key to Termius and create a new host for connection.

Prerequisites

You’ll need the corresponding server details for SSH connection, such as the IP address or hostname, SSH port, username, and an SSH key.

Also, make sure you have the latest Termius version on your device (available on macOS, Windows, Linux, iOS, and Android)

Add an SSH key

1. Navigate to Settings -> Keychain.

2. Click on the Key button.

3. Paste the private key manually or Import a key from your filesystem.

Add a Host

1. Navigate to Hosts and click the New Host button.

2. In the New Host form that appears, provide the following details:

   • IP address

   • Port - the default SSH port is 22. Leave empty for default or specify a custom port.

   • Username

3. Click the Key button.

4. Select a key from a list of available SSH keys.

5. Hit the Connect button.

Once the first connection starts to a host, Termius prompts you to add a fingerprint to known hosts; press the Add and Continue to establish a connection. If something goes wrong, Termius shows you a connection log, which you can use to troubleshoot your connection.
