# Other settings

## Custom CA certificates

The Efento Gateway comes with several commonly used **preloaded CA certificates**. If you wish to use a **custom CA certificate**, you can upload it through the gateway by navigating to **Settings > CA Certificates**.

Efento Gateway supports any certificate in PEM format. For security reasons, we strongly recommend using certificates signed by a trusted Certification Authority. However, for development or demonstration purposes, you may also [use a self-signed certificate](/efento-gateways/integration/self-signing-ca-certificate.md).

## Proxy

The Efento Gateway can connect to **Efento Cloud** or a **third-party server** through a proxy server. By default, the proxy feature is **disabled**. Efento Cloud supports both **anonymous** and **non-anonymous** proxy servers.

To configure proxy settings:

1. Go to the **Settings > Proxy** tab.
2. Select the **proxy type**.
3. Enter the **server address** and **port**.
4. If using a **non-anonymous proxy**, provide the **login credentials**.

These settings allow the gateway to communicate with the server securely and reliably through your network’s proxy.

## Encryption

Communication between Efento loggers and the Efento Gateway can be **encrypted** using a user-defined key. When encryption is enabled, only devices that have the correct key can decode the transmissions and read loggers measurements.

The gateway allows you to add up to **five encryption keys**. Once a key is added, the gateway can decrypt and read measurements from all loggers using that same key. Encryption keys for loggers can be [configured using the **Efento mobile application**](/efento-ble-loggers/using-loggers/standalone-mode/logger-settings.md#encryption).

## Password

In the **Settings** > **Password** tab, you can change the gateway’s login password. To update the password, enter the **new password twice** and provide the **current password** for verification. It is **strongly recommended** to change the password during the initial gateway configuration to ensure secure access.

## Reset

The **Settings > Reset** tab allows you to manage the gateway’s restart and factory reset functions:

* **Restart the Gateway:** The device will power off and on again without affecting any existing settings or configurations.
* **Reset the Gateway:** The device will restore **factory default settings**. All custom configurations will be lost, and the gateway will need to be reconfigured.

A factory reset can also be performed using the physical button on the back of the gateway:

* **Older models:** Press and hold the button for **10 seconds**.
* **Newer models:** Press the button **7 times** in succession.
