 ## Authentication
 
-### Get Token Details
+The Deepgram Python SDK supports multiple authentication methods to provide flexibility and enhanced security for your applications.
+
+### Authentication Methods
 
-Retrieves the details of the current authentication token.
+#### API Key Authentication (Traditional)
+
+The traditional method using your Deepgram API key:
 
 ```python
-response = deepgram.manage.rest.v("1").get_token_details()
+from deepgram import DeepgramClient
+
+# Direct API key
+client = DeepgramClient(api_key="YOUR_API_KEY")
+
+# Or using environment variable DEEPGRAM_API_KEY
+client = DeepgramClient()  # Auto-detects from environment
+```
+
+#### Bearer Token Authentication (OAuth 2.0)
+
+Use short-lived access tokens for enhanced security:
+
+```python
+from deepgram import DeepgramClient
+
+# Direct access token
+client = DeepgramClient(access_token="YOUR_ACCESS_TOKEN")
+
+# Or using environment variable DEEPGRAM_ACCESS_TOKEN
+client = DeepgramClient()  # Auto-detects from environment
 ```
 
-[See our API reference for more info](https://developers.deepgram.com/reference/authentication).
+### Authentication Priority
+
+When multiple credentials are provided, the SDK follows this priority order:
+
+1. **Explicit `access_token` parameter** (highest priority)
+2. **Explicit `api_key` parameter**
+3. **`DEEPGRAM_ACCESS_TOKEN` environment variable**
+4. **`DEEPGRAM_API_KEY` environment variable** (lowest priority)
+
+### Environment Variables
+
+Set your credentials using environment variables:
+
+```bash
+# For API key authentication
+export DEEPGRAM_API_KEY="your-deepgram-api-key"
+
+# For bearer token authentication
+export DEEPGRAM_ACCESS_TOKEN="your-access-token"
+```
 
-### Grant Token
+### Dynamic Authentication Switching
 
-Creates a temporary token with a 30-second TTL.
+Switch between authentication methods at runtime:
 
 ```python
-response = deepgram.auth.v("1").grant_token()
+from deepgram import DeepgramClient, DeepgramClientOptions
+
+# Start with API key
+config = DeepgramClientOptions(api_key="your-api-key")
+client = DeepgramClient(config=config)
 
+# Switch to access token
+client._config.set_access_token("your-access-token")
+
+# Switch back to API key
+client._config.set_apikey("your-api-key")
 ```
 
-[See our API reference for more info](https://developers.deepgram.com/reference/token-based-auth-api/grant-token).
+### Complete Bearer Token Workflow
+
+Here's a practical example of using API keys to obtain access tokens:
+
+```python
+from deepgram import DeepgramClient
+
+# Step 1: Create client with API key
+api_client = DeepgramClient(api_key="your-api-key")
+
+# Step 2: Get a short-lived access token (30-second TTL)
+response = api_client.auth.v("1").grant_token()
+access_token = response.access_token
+
+# Step 3: Create new client with Bearer token
+bearer_client = DeepgramClient(access_token=access_token)
+
+# Step 4: Use the Bearer client for API calls
+transcription = bearer_client.listen.rest.v("1").transcribe_url(
+    {"url": "https://dpgr.am/spacewalk.wav"}
+)
+```
+
+### Benefits of Bearer Token Authentication
+
+- **Enhanced Security**: Short-lived tokens (30-second expiration) minimize risk
+- **OAuth 2.0 Compliance**: Standard bearer token format
+- **Scope Limitation**: Tokens can be scoped to specific permissions
+- **Audit Trail**: Better tracking of token usage vs API keys
+
+### Authentication Management
+
+#### Get Token Details
+
+Retrieves the details of the current authentication token:
+
+```python
+response = deepgram.manage.rest.v("1").get_token_details()
+```
+
+#### Grant Token
