+#### 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")

+#### Anonymous authentication
+```python
+from pyartifactory import Artifactory
+art = Artifactory(url="ARTIFACTORY_URL", anonymous_auth=True)
