I want to use authetication addition and protect the some pages with password.How can use this addition?Is there any documentary?
What platform? What product?
System 800xA have plenty authentication mechanisms, to display a graphic aspect "Read" access is required on the object owning the aspect. Revoke read access to prevent displaying content from an object.
There is no password control available in PG2, so I suggest using the LogOver feature to a higher user account where required. Read more in the users guides.
