(info) You need to be a Confluence administrator to enable Captcha.

If your Confluence site is open to the public you may find that automated spam is being added, in the form of comments or new pages.

Captcha is the technical term for a test that can distinguish a human being from an automated agent such as a web spider or robot.

When Captcha is switched on, users will need to recognise a distorted picture of a word, and must type the word into a text field. This is easy for humans to do, but very difficult for computers.

You can configure Confluence to enforce Captcha for certain types of users. You can exempt logged-in users (they will have completed a Captcha when they signed up), or members of particular groups.

By default, Captcha images will not be shown to logged-in users. Only anonymous users will have to perform the Captcha test when creating comments or editing pages.

To enable Captcha for Confluence,

  1. Go to the 'Administration Console' view. To do this:

    • Go to a page in the space and choose 'Administration' from the 'User' menu, which is labelled with your Confluence username. The 'Administration Console' view will open.
  2. Select Spam Configuration' from the 'Configuration' menu on the left.
  3. Turn on Captcha by clicking the 'ON' link.
  4. 特定のグループに対して、キャプチャを無効にする場合
    • Select 'No one' if you want everyone to see Captchas.
    • Select 'Signed in users' if you want only anonymous users to see Captchas.
    • If you want everyone to see Captchas except members of specific groups, select the 'Members of the following groups' and enter the group names in the text box.
      You can click the magnifying-glass icon to search for groups. Search for all or part of a group name and click the 'Select Groups' button to add one or more groups to the list.
    • リストからグループを削除するには、グループ名を削除します。
  5. 「保存」ボタンをクリックします。
