# Quick start

Termius is an SSH client for connecting to remote hosts, managing infrastructure, and running terminal sessions across devices. 

With a paid subscription, there is no limit on the number of devices you can use. Termius is available on macOS, Windows, Linux, iOS, and Android, so you can use it across all your devices.

See [Download Termius](https://docs.termius.com/getting-started/download-termius).

## Install Termius

{% stepper %}
{% step %}

#### Download and install Termius on your device

Termius is supported on macOS, Windows, Linux, iOS, and Android. Use it across all your devices. See [Download Termius](https://docs.termius.com/getting-started/download-termius)
{% endstep %}

{% step %}

#### Sign in or create an account

When you open the app for the first time, you will be asked to **sign in** or **create an account**.

Creating an account starts a **Pro trial**. You will not be charged automatically when the trial ends. After the trial, you can choose to subscribe or downgrade to the **Starter** plan.\
Learn more about plans in [Billing and plans](https://docs.termius.com/administration/billing-and-plans#h_01jr7a3h6qnpeab58wn5dy60ey)

You can also use Termius locally without an account by logging out after the trial.
{% endstep %}

{% step %}

#### Save your Encryption Password

When creating an account, you must set an **encryption password**. This password is used to encrypt and decrypt your data. Even if you choose to sign up with Google, you still need to specify a separate encryption password to secure your data.

{% hint style="danger" %}
Store it securely, for example, in a password manager.

If you forget your **Encryption Password**, Termius cannot decrypt your data, and you will need to reset your account and lose all stored data.
{% endhint %}
{% endstep %}
{% endstepper %}

## Connect to a host

Once your account is created and you are logged in, you can create your first host.

{% stepper %}
{% step %}
Click `New Host`

{% endstep %}

{% step %}
Enter the **IP address**, **port**, **username,** and **password**.\
Termius auto-saves your host.

{% endstep %}

{% step %}
Double-click the host in the list or click `Connect`

{% endstep %}
{% endstepper %}

Once the connection is established, you will see the terminal where you can control your host and run commands. Termius will also auto-detect the operating system on your host and update the host icon accordingly.

See [Connecting to a server](https://docs.termius.com/organize-and-connect-to-hosts/connecting-to-a-server) for a more complete review of supported protocols and host settings.

## Explore Termius Settings

Termius aims to provide users with meaningful default settings. Some of these settings can be customized to accommodate your existing habits.

Navigate to `Termius > Settings > Terminal` or `Termius > Settings > Shortcuts` to customize your terminal experience in Termius.

## What to do next

Now that you’ve connected to your first host, continue with setting up Vaults to securely store and organize your hosts, credentials, and snippets. With a paid subscription, Vaults sync your data across devices and enable secure sharing with your team.
