Sensitive data are WiFi Logins and authentication data. This is done in preparation for the OTA update, where the firmware image will be transferred unencrypted and therefore passwords could be extracted from a dumped image.

## Setup notes
|
|
|
|
Authentication data for WiFi connections and OTA firmware updates is stored in the SPIFFS. You must create the following files:
|
|
|
|
### `data/etc/wlan`
|
|
|
|
This file contains WiFi logins. Each entry consists of two lines: The first line contains the SSID to connect to, the second the password.
|
|
|
|
### `data/etc/auth`
|
|
|
|
This file configures the authentication at the device. For now, this is used for OTA updates.
|
|
|
|
The file contains two lines: First the password, second the salt.
|
|
|
|
The salt must be known to any client performing OTA updates and can be stored in a local configuration file. The password should never be stored in any config file.
