Your Flowella verification code is . It expires in minutes. Do not share it with anyone.
Authentication codes that arrive where people look.
OTP over WhatsApp.
Use WhatsApp for high-visibility one-time passwords, login approvals, and step-up verification. Keep the CRM informed without turning security into a support ticket.
The OTP blueprint.
Generate the code, send it over WhatsApp, branch on verification status, retry once, then fail closed or escalate.
Copy that keeps trust high.
Authentication templates are short, transactional, and explicit about expiry.
Your new verification code is . Use the latest code only.
We could not verify this request. For your safety, the action has been paused and support can help.
Five things that make authentication less painful.
Sends the code on WhatsApp - faster visibility than email for mobile-first users.
Expires codes quickly - the code is short-lived and tied to the attempted action.
Branches on verification - success exits immediately, failure retries once.
Fails closed - repeated failure creates a safe support path, not an unlocked account.
Logs the event - HubSpot receives the verification outcome for audit and support context.
Why WhatsApp OTP works.
Authentication is only useful when the user sees the code quickly and the system handles failure safely.
01 Why delivery matters
WhatsApp brings OTP delivery to the channel users already monitor on mobile, reducing email delays and failed attempts.
- Silent after "yes" — wire your Flow to the CRM milestone (donation cleared, booking confirmed, ticket closed) and let the thread go quiet the instant the job is done. No duplicate ask, no nudge — one trustworthy conversation people actually open next time.
02 How to enhance it
Add risk scoring, device fingerprinting, high-value transaction approval, and automatic lockout escalation.
03 Gotchas
Never reuse codes, avoid exposing account details in templates, rate-limit retries, and keep support scripts ready for false positives.
The point: OTP should be fast for the real user and boringly strict for everyone else.
