 Preserving User WiFi Credentials
 --------------------------------
 
-To be written...
+If you purchase a device, or install ESPHome on a device that does not have Wi-Fi credentials pre-configured from YAML,
+ESPHome will now preserve any credentials entered via the :doc:`/components/captive_portal`, :doc:`/components/improv_serial`
+or :doc:`/components/esp32_improv` components after an OTA update of the firmeware is done. It is possible they can survive
+flashing via serial, but only if the flash was not erased first, which it is in the case of using ESPHome to flash.
+
+Products that use `ESP Web Tools <https://esphome.github.io/esp-web-tools>`__ are able to specify in the manifest that the flash
+should not be erased when installing the firmware and this is a way to provide updates for a device that was sold.
