 transparent to your application (there is no need to modify your code), and you
 only need to supply your Auth0 configuration parameters.
 
+### Using the CLI
+
+To configure Auth0 via the CLI, navigate to the folder where your project files are and make sure you've set your [API key.](../quickstart/apikey.md) Now run:
+
+```sh
+ploomber-cloud templates auth0
+```
+
+The Auth0 template requires your project to be initialized. If it hasn't been initialized yet, you can initialize it on the spot. You should see something like this:
+
+```sh
+Project must be initialized to continue. Would you like to initialize? [y/N]: y
+Initializing new project...
+Inferred project type: 'your-project-type'
+Is this correct? [y/N]: y
+Your app 'project-name-1999' has been configured successfully!
+To configure resources for this project, run 'ploomber-cloud resources' or to deploy with default configurations, run 'ploomber-cloud deploy'
+```
+
+If your project has already been initialized, you won't see this. You'll then be prompted to enter three credentials from Auth0:
+
+1. `AUTH_SECRET`
+2. `AUTH_CLIENT_ID`
+3. `AUTH_ISSUER_BASE_URL`
+
+These can be obtained from your Auth0 application page. If you haven't yet created an application, log into Auth0 and create one. Then find the credentials here:
+
+![](../static/password/auth0-credentials.png)
+
+Once you've entered your credentials, you should see a confirmation like this:
+
+```sh
+Successfully configured auth0. To deploy, run 'ploomber-cloud deploy'
+```
+
+```{note}
+If you already created an `.env` file, these credentials have been be saved there (along with your other secrets). If you haven't, one has been be created for you with the credentials saved.
+```
+
+Now, run `ploomber-cloud deploy` to deploy your project.
+
+### Set /callback and /status URLs
+
+Almost done! We just need to set the `callback` and `logout` URLs for your Auth0 app. Navigate to your Ploomber project's application page and copy the application URL. It should look like `https://application-name-1999.ploomberapp.io`.
+
+Now, go back to the Auth0 application page and scroll down to `Application URIs`. Set these values:
+
+- Allowed Callback URLs: `https://application-name-1999.ploomberapp.io/callback`
+- Allows Logout URLs: `https://application-name-1999.ploomberapp.io/status`
+
+It should look like this:
+
+![](../static/password/auth0-urls.png)
+
+```{tip}
+If you ever re-initialize and deploy your app under a different name, you'll have to update these URLs.
+```
+
+You're all set! Once your application has finished deploying, click `View Application`. You should be met with Auth0 authentication:
+

+
+Simply login and you'll be re-directed to your application.
