Before making production changes: exact screen names and platform behavior can change as GoHighLevel, Android, carriers, and the underlying messaging platform evolve. Test changes on a controlled deployment first.

Use OTP for a defined verification event

Examples include verifying that a user controls a phone number before a higher-value account action.

Security basics

  • Use short expiration windows.
  • Limit verification attempts.
  • Do not log OTP values unnecessarily.
  • Rate-limit requests by user/device/IP as appropriate.
  • Do not treat SMS OTP as phishing-proof or SIM-swap-proof.

Developer testing

Test request, delivery, verification, expiration, invalid-code, and resend behavior before production.
