Captcha Type

Learn how to set up Portal Captcha or Join-CAPTCHA in Guardian to screen new members and keep bots out of your Telegram group.

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.

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

Portal Verification steps for users:

Tap the button to verify

Launch Guardian (appears the first time you use)

Click Verify in the miniapp that launched and you're in!

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.
