+## 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>**<br>
+   6a. (optional) If your OTP cannot be safed, try to paste your OTP code via MQTT to the following topic: `volvoAAOS2mqtt/otp_code` <p>
+       <details>
+             <summary>OTP Post Script</summary>
+             <div>
+                <p>
+                1. Safe the following script in your script section <br>
+                2. Go to https://yourHAUrl/developer-tools/service<br>
+                3. Search for "Post Volvo OTP"<br>
+                4. Tick "OTP" and fill in your OTP<br>
+                5. Run this service<br>
+             </div>
+       
+            alias: Post Volvo OTP
+            sequence:
+              - service: mqtt.publish
+                metadata: {}
+                data:
+                  topic: volvoAAOS2mqtt/otp_code
+                  payload: "{{ otp }}"
+            mode: single

+                name: OTP
+                description: Volvo OTP
+   
+   </details>
+8. 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.
