# Captcha Type

Guardian offers two options for screening new members at the door.

**Portal Captcha (recommended)** New members are directed to your portal channel, where they complete a simple verification before being admitted to the group.

{% column valign="middle" %}
To enable, type **/settings** in your group chat, choose whether to open settings in private or in group, then tap **Entry Security** > **CAPTCHA** > **Portal**.

{% endcolumn %}

**Join-CAPTCHA** Prefer not to use a portal but still want to keep bots out? Join-CAPTCHA lets you keep your group public while muting new members until they complete verification.

To enable, type **/settings** in your group chat, choose whether to open settings in private or in group, then tap **Entry Security** > **CAPTCHA** > **Join-CAPTCHA**.
