# Identities
## Overview
An **identity** in Termius stores a username, password, and key together. Link an identity to multiple Hosts or Groups to reuse the same credentials without duplication.
Identities are stored in vaults. Vaults protect your data with end-to-end encryption. For details, see [Encryption overview](/security/encryption-overview.md).
{% hint style="info" %}
Autocomplete can paste passwords from identities. When a password prompt appears in the terminal, Termius suggests the stored password.
{% endhint %}

{% endtabs %}
## Link an identity to a host
{% tabs %}
{% tab title="Desktop" %}
To link an identity to a host on the desktop:
1. Open the `Hosts` screen, right-click the host, and select `Edit Host Details`
2. In the Credentials section, click the `Username` field and select an identity
{% endtab %}
{% tab title="iOS" %}
To link an identity to a host or group on iOS/Android:
1. Open the `Hosts` screen. Tap the host icon, then tap the edit icon.
2. Tap the user icon on the right side of the `Username` field, then select an identity
{% endtab %}
{% tab title="Android" %}

{% endtabs %}
{% hint style="info" %}
When working with multiple vaults, if you don't see your identity in the list, make sure the identity and the host are in the same vault.\
\
To choose the vault where your identities are stored, click `Credentials from` in the Credentials section, and select the vault.
{% endhint %}
## Use identities in Autocomplete
When Termius detects a password prompt in the terminal, it can suggest identities with stored passwords. This is useful for `sudo` prompts.
