+title: "Generate a Development Token"
+description: "In this tutorial we will show you how to generate a development token for the self-hosted [PowerSync Service](https://powersync.mintlify.app/architecture/powersync-service#powersync-service)."
+---
+
+<Steps>
+    <Step title={"Generate a SharedSecret"}>
+        To generate a SharedSecret, you can use this [Online JWS key generator](https://8gwifi.org/jwsgen.jsp):
+        <Note>
+            You don't need to edit the default payload in the [Online JWS key generator](https://8gwifi.org/jwsgen.jsp).
+            You simply need a valid `SharedSecret` value.
+        </Note>
+        - Click `Generate JWS Keys`
+        - Copy the `SharedSecret` value
+        <Warning>
+            Using an online key generator for secrets in a production environment is not recommended.
+        </Warning>
+    </Step>
+
+    <Step title={"Update powersync.yaml"}>
+        Update the `k` value in the jwks keys in your `powersync.yaml` config file with the `SharedSecret` value copied in the previous step:
+        ```yaml powersync.yaml {8}
+        # Client (application end user) authentication settings
+        client_auth:
+            # JWKS URIs can be specified here
+            jwks_uri: !env PS_JWKS_URL
+            jwks:
+                keys:
+                    - kty: 'oct'
+                    k: 'YOUR_GENERATED_SHARED_SECRET'
+                    alg: 'HS256'
+        ```
+    </Step>
+
+    <Step title={"Generate a development token"}>
+        1. If you have not done so already, clone the [powersync-service repo](https://github.com/powersync-ja/powersync-service/tree/main) repo
+        2. Install the dependencies
+            - In the project root, run the following commands:
+                ```bash
+                pnpm install
+                pnpm build:packages
+                ```
+            -  In the `test-client` directory, run the following commands:
+                ```bash
+                pnpm build
+                ```
+        3. Generate a new token by running the following command in the `test-client` directory with your updated `powersync.yaml` config file:
+            ```bash
+            node dist/bin.js generate-token --config path/to/powersync.yaml --sub test-user
+            ```
+            You should see an output similar to the following:

+    </Step>
+</Steps>
