Cross-Group Trust on Telegram

Returning members skip repeat captchas in your Telegram group. Enable Cross-Group Trust in /settings with @doublegram_captcha_bot — users verified in other Captcha-protected groups auto-approve when they meet your minimum verifications and time window.

Cross-Group Trust in @doublegram_captcha_bot reduces friction for real humans who already proved themselves in another Captcha-protected Telegram community. Instead of mute + Mini App again, they get an instant auto-verified message and can speak immediately.

How it works

  1. User completes captcha successfully in any Telegram group protected by @doublegram_captcha_bot.
  2. The bot increments their global trust score (success count + timestamp).
  3. When they join your Telegram group, the bot checks your trust settings.
  4. If they qualify → skip mute and captcha → short success message in the group.
  5. If not → normal mute + Verify Captcha flow.

Default behavior

Trust is enabled by default for new groups with:

  • Minimum verifications: 1
  • Validity window: 30 days since last successful verification

What members see when trusted

A message like: ✅ [user] has been automatically verified (trusted user).

If Silent Mode is on in /settings, this message may be auto-deleted after the configured delay.

Security note: Trust is global across @doublegram_captcha_bot deployments — a user verified in another protected Telegram group counts toward trust. Raise minimum verifications if you want stricter entry.

Who never gets trust skip?

  • First-time users with zero successful @doublegram_captcha_bot verifications
  • Users whose last success is older than your max-days setting
  • Groups where trust is disabled in /settings

Quick reference

  • Default: ON, 1 verification, 30 days
  • Configure: /settings → Cross-Group Trust
  • Benefit: skip captcha for proven humans
