About Passphrase Feature

The Passphrase feature, in conjunction with the About Confirm Feature, restricts web access based on a passphrase or password. You can configure the passphrase operation for special URI categories or domains in the Forbidden URI List. To access the forbidden URIs, users are asked to enter the correct password or else web access is blocked.

Passphrase only works for HTTP requests. HTTPS requests cannot be redirected to a Passphrase page.

How the Passphrase operation works

1. The user attempts to access a restricted website.
2. A Passphrase page displays on the user’s browser.
3. The user must enter the passphrase or password and submit it.

4. CFS validates the submitted passphrase or password with the website’s password:

   • If the passphrase or password matches, web access is allowed. No further confirmations are needed and users can continue to access websites of the same category for the Active Time period set for the Confirm feature. The default is 60 minutes.

   • If the passphrase or password does not match, access is blocked, and a Block page is sent to the user.

     Users have three chances to enter the correct passphrase or password. The site is blocked if all chances fail.

   If the user selects Cancel, the site is blocked immediately.
