If you're a new developer, you may be unfamiliar with command-line interfaces and consoles. In this article, we'll provide an introduction to Terminal Emulators and the Termius client terminal.

**Terminal Emulators**

Terminal emulators are software programs that allow users to access their computer's operating system through commands. These commands can be used to open and edit files, move files around, launch applications, and more. Terminal emulators are frequently used by businesses to access data or programs on remote devices or servers.

**What is [Termius](https://termius.com/)?**

Termius is a client terminal with built-in Telnet and SSH support. It allows users to launch multiple concurrent Telnet sessions with SSH support and manage Mosh connections securely. It also provides full emulation of the Emacs editor, Vim text editor, and many other CLI tools, exactly how you would expect them to work on your computer. Termius is available for Linux, Windows, Mac, iOS, and Android platforms.

Termius features powerful tools such as group hosting, tagging for easy search, rich previews of data items, and secure sync AES-256. Hosts, Port Forwarding rules, Snippets, and Keys are all client-side encrypted. Other helpful features include autocompleting saved sessions and quick connection to previously connected hosts' snippets history.

**What sets Termius apart?**

Termius is the ultimate solution for managing UNIX and Linux systems. Whether it's a local machine, remote service, Docker Container, VM, Raspberry Pi, or an AWS instance, Termius has got you covered. It is essentially Putty for Android, but with a sleek and modern design.

Let's take a closer look at Termius on three fundamental bases.

_1. Security:_ Termius has end-to-end encryption that was a part of the sync from day one. The first version was released about eight years ago with crypto algorithms that were designed at the same time. Since then, Termius has kept up with the changing crypto space by using known experts and conventional algorithms for its encryption. Termius uses libsodium and Botan for all crypto-related operations, and more details about the implementation can be found in the official documentation. Termius also offers the ability to time your update, ensuring an easy process for the end user. Plus, SSH to a server with Face ID or Touch ID allows for added security, using keys that can't be stolen from your device.

_2. Ease of use:_ Termius makes managing infrastructure and credentials easy and logically structured. Operational teams can keep information about the current configuration of infrastructure up to date by using tools like group hosting, tagging, and rich previews of data items. The app's autocompleting saved sessions and quick connection to previously connected hosts' snippets history make accessing the information you need fast and efficient.
