Attack protection mode

Status#

A separate adaptive CAPTCHA attack mode is not available as a working setting. This page does not provide instructions to enable it. The Anti-raid — Coming soon entry also does not mean that protection is active.

Available protection#

Configure ordinary CAPTCHA: choose in-group or join-request verification, a challenge type, a time limit and a failure action. Check bot permissions and test the flow with a test member.

Do not rely on an automatic switch to stronger verification during a surge of arrivals. Use the Telegram controls and group restrictions you have verified.
