   Authentication is an enterprise feature. To get access, [contact sales](mailto:[email protected]).

-As the name suggests, Authentication offers full privacy for all of your
-documentation content. This includes all of the following:
+Authentication offers full privacy for all of your
+documentation content by requiring users to authenticate before viewing any content, such as:
 
 - Documentation page content
 - Images used in documentation pages
 - Search results
 - AI chat interactions
 
-Authentication can be thought of as Personalization + privacy. In addition
+You can authenticate users through handshake methods such as:
+
+- [Password](./authentication-setup/password)
+- [JWT](./authentication-setup/jwt)
+- [OAuth](./authentication-setup/oauth)
+- [Mintlify dashboard](./authentication-setup/mintlify)
+
+
+Authentication is similar to our [Personalization](./personalization) offering, but with guaranteed privacy. In addition
 to securing your documentation content, all features that are available via
-Personalization are also available via Authentication. For more information
-about the features of Personalization, [visit our docs on Personalization](./personalization).
