+## OTP Authentication
+
+As of version <b>v1.9.0</b>, this addon uses the same OTP authentication as the Volvo app. 
+The following steps are required for authentication in exactly this order:
+
+1. Setup volvo2Mqtt, either via Docker, or via HA addon (take a look at the "Setup" section below)
+2. Fill in your settings and start volvo2Mqtt
+3. Your log will show the following lines <br> 
+```Waiting for otp code... Please check your mailbox and post your otp code to the following mqtt topic "volvoAAOS2mqtt/otp_code". Retry 0/15```<br>
+```Waiting for otp code... Please check your mailbox and post your otp code to the following mqtt topic "volvoAAOS2mqtt/otp_code". Retry 1/15```<br>
+```etc ...```
+4. Now, open your mailbox and copy your OTP Code
+5. Open HomeAssistant and search for the entity ID ```text.volvo_otp```
+6. Paste your OTP into the text entity and **<ins>press Enter</ins>**
+7. If everything has worked, your addon is now authenticated. In the future, OTP authentication only needs to be done when updating, not when restarting the container.
+
