 Since Artifactory 6.6.0 there is version 2 of the REST API for permission management, in case you have that version or higher, you need to pass api_version=2 to the constructor when you instantiate the class.
 
+#### Basic authentication
 ```python
 from pyartifactory import Artifactory
 art = Artifactory(url="ARTIFACTORY_URL", auth=('USERNAME','PASSWORD_OR_API_KEY'), api_version=1)
 ```
 
+#### Authentication with access token
+```python
+from pyartifactory import Artifactory
+art = Artifactory(url="ARTIFACTORY_URL", access_token="your-access-token")
+```
+
+Note:
+* If you set both `access_token` and `auth`, the access_token authentication will be chosen
+* If you do not set any authentication method, API calls will be done without authentication (anonymous)
+
 ### SSL Cert Verification Options
 
 Specify a local cert to use as client side certificate
