A CAPTCHA is a program that can tell whether its user is a human or a computer. CAPTCHAs are used by many websites to prevent abuse from bots, or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.

ロケーション: サイト管理 > ユーザ > 認証 > 認証の管理 > 設定

認証の管理ページにある、共通設定の「自己登録」が選択された場合、この認証方法ではユーザが自分自身でアカウントを作成することができます。アカウントを確認するため、ユーザのアカウントプロファイルで指定したメールアドレス宛にメールが送信されます。

Warning: Enabling self registration results in the possibility of spammers creating accounts in order to use forum posts, blog entries etc. for spam. This risk can be minimized by limiting self registration to particular email domains with the allowed email domains setting in Administration > Users > Authentication > Manage authentication (or in Administration > Server > Email prior to Moodle 1.9). Alternatively, self registration may be enabled for a short period of time to allow users to create accounts, and then later disabled.

Note: The Email-based self-registration authentication plugin must be enabled to allow users who previously self-registered to login. Selecting Email-based self-registration as the self registration method allows potential users to self register.

CAPTCHAを使用した新しいアカウントの作成フォーム

A CAPTCHA is a program that can tell whether its user is a human or a computer. CAPTCHAs are used by many websites to prevent abuse from bots, or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.

Moodle 1.9

From Moodle 1.9.1 onwards, spam protection may be added to the email-based self-registration new account form with a CAPTCHA element - a challenge-response test used to determine whether the user is human.

In addition to enabling the reCAPTCHA element, email-based self-registration should be set as the self registration authentication plugin and reCAPTCHA keys should be set in the manage authentication common settings.
