official ESPHome documentation OTA encryption password migration existing devices

💡 Result:

ESPHome’s current official migration guide says **don’t replace the OTA password with encryption in one step**. First update the device to firmware that offers encrypted OTA, while keeping the password in your config; then require encryption and remove the password. The procedure requires ESPHome **2026.9.0 or newer**. ([esphome.io](https://esphome.io/components/ota/esphome/?utm_source=openai))

- **With the native API:** Ensure the existing API encryption key is in your YAML—don’t generate a new key for a Home Assistant–provisioned device. Update with the password still configured, then add OTA `encryption:` and remove `password:` for the next update.
- **Without the native API:** The guide uses a temporary API block and key for the first update; then it moves that same key to OTA encryption and removes the password.

Check the device log for **“Encryption: offered, plaintext accepted”** after the first update and **“Encryption: required”** after the second. ([esphome.io](https://esphome.io/components/ota/esphome/?utm_source=openai))

The OTA docs also clarify that a password authenticates the uploader but does not encrypt the firmware in transit; OTA `password:` and `encryption:` cannot be configured together. ([esphome.io](https://esphome.io/components/ota/esphome/?utm_source=openai))

Document the staged OTA migration for existing devices.

This snippet can strand devices running the current password-based firmware. ESPHome requires an intermediate update before the device can require encrypted OTA. Limit this snippet to new devices or devices that already support encrypted OTA, and document the two-step migration. The migration requires ESPHome 2026.9.0 or newer, while these configurations currently allow 2026.8.0.

Update the OTA migration comments in the configuration guidance to limit the
direct encrypted-OTA change to new devices or devices already supporting
encrypted OTA. Document the two-step migration for password-based devices: first
deploy firmware that offers encrypted OTA while retaining password acceptance,
then remove the password in a subsequent update; note the ESPHome 2026.9.0
minimum requirement.
