Termius is an SSH, Mosh and Telnet client with data sync and collaboration features. Termius works on Windows / Mac / Linux as well as mobile devices – iOS / iPadOS and Android. Some of its features are provided through the Pro or Teams subscriptions – see this page for more info on the plans.

Installing Termius

To learn how to download and install Termius, take a look at these instructions.

When you launch the app for the first time, it suggests that you create an account.

An account is required, if you're going to use the features included in the paid plans, such as cross-device data synchronization. Once you create an account, you're offered or automatically provided with a 14-day trial period, during which you can use the features of the Pro subscription for free.

Connecting to a host

Adding a host entry is probably the first thing you'll want to do after the installation. That will allow you to connect to a remote device with an SSH, Mosh or Telnet server installed.

Double-click or tap a host entry to connect to the device that the entry represents. There's no need to provide credentials upon connection if you've saved them in the entry.

Here you can read more about support for the SSH, Mosh and Telnet protocols in Termius.

Connecting using ssh keys

If you're going to authenticate using an ssh key, you'll need to import it to / generate in Termius. Importing can be done in the 'Keychain' section or when you're adding or editing a host.

A key can be generated in the 'Keychain' section.

Setting up identities

When you have several hosts requiring the same credentials, check out identities.

If you save those credentials in an identity and link it with the hosts, you won't have to update every single host when the credentials for those hosts need to be replaced – just the identity.

See this doc for more info on authentication in general and identities in particular.

Organizing hosts with groups and tags

For easy navigation and more, you can categorize hosts with groups and tags. Groups can be used not only for orderliness – a group's properties are inherited by non-explicitly specified parameters in the nested hosts.

See these articles for more info on groups and tags.

Running snippets

Snippets are saved commands that you can run with a single click or tap, while in the terminal, or auto-run right after you connect to a host. On mobile devices, you can run a snippet on several hosts at once.

Transferring files (SFTP)

Termius comes with an SFTP client allowing you to securely transfer files between the local and a remote host or two remote hosts as well manage and edit files on a remote and/or the local host.
