Termius provides several ways to customize your terminal experience. You can select from a choice of professionally-designed themes or change your font and font size to match your tastes.

Setting a Default Theme and Font

When you set a default theme and font, you define that value for hosts you add in the future. Hosts already added will not take on the default theme and font settings.


Tap Settings from the main menu, then select your preferred default theme and font parameters.

Windows and Linux

Click the ☰ icon in the top right corner and click File, then Preferences. On this page you can choose your default theme and font parameters.


Click the Termius menu at the top and click Preferences, or press Command + Comma (,).

Changing Theme and Font Settings on an Existing Host

Theme and font settings can be changed per host, and these settings will persist regardless of a change to the default theme or font settings.


Tap on Hosts then tap and hold the host you wish to adjust. Then tap the edit icon immediately to the left of the red trash can icon and scroll down to the theme and font settings.

When done, click Save.

Session Settings

Keep-Alive Interval

Termius can send a SSH keep-alive packet every so often. This is helpful on slow or intermittent connections. You can set this to 0 to disable, or specify a value.

If you find your connection disconnecting often, try setting this to 30 to 60 seconds.

Bell Sound

The terminal can send a bell sound to the user (usually on failed backspaces or for alerts). Some users may find this annoying, so it can be disabled.

Host OS Detection

When Termius connects to a remote host it can automatically detect the operating system. This setting is on by default, but can be disabled.

Additional Keyboard Customization on Mobile

On mobile devices, Termius allows you to bind the volume up, down, and shake activities to keys like backspace, enter, key up, etc.

PIN Code / TouchID / FaceID on Mobile

On mobile devices, Termius allows you to optionally configure a PIN code or utilize TouchID / FaceID (iOS) to protect your data.
