What is a WhatsApp authentication template?

WhatsApp Authentication Templates are a Meta-approved message category built specifically for sending one-time passcodes and verification codes over the WhatsApp Business API. Your OTP shows up in the app your customers already check dozens of times a day, with a built-in Copy Code button so they never have to retype a single digit.

How businesses use whatsApp authentication templates

From payment confirmation to account recovery, WhatsApp authentication templates are perfect for various secure messages.

Login verification

Confirm it's really your customer before granting account access, without adding friction to the sign-in flow.

Password & PIN resets

Send a secure code the moment a customer requests a reset so they're never stuck waiting on a delayed email.

Transaction & payment confirmation

Add a verification step before high-value actions are complete, right inside the app customers already trust.

Account recovery

Help locked-out customers regain access fast, with a code that's effortless to copy and hard for anyone else to intercept.

What you get with WhatsApp authentication templates

From payment confirmation to account recovery, WhatsApp authentication templates are perfect for various secure messages.

Fewer abandoned verifications

WhatsApp messages arrive and are read in seconds, and with Copy Code, customers act immediately instead of losing time.

Hidden from team inbox

OTPs are masked the moment they arrive. Agents can see that a code was sent (never the code itself), closing off an insider risk most WhatsApp verification flows leave open.

Meta-approved

Authentication templates run through their own dedicated meta-review category, so you launch with a compliant, pre-vetted message format from day one—no back-and-forth rejections.

Auto-expiring codes

Set how long each OTP stays valid, down to the minute. Once that window closes, the code is useless, blocking replay attacks before they can happen.

Frequently Asked Questions

Do I need separate Meta approval for authentication templates?

Yes. Authentication templates are reviewed and approved under their own dedicated category, separate from Marketing and Utility templates.

Can I customize the wording of an authentication message?

Customization is intentionally limited. Meta restricts free text in authentication templates (no emojis, no marketing language) to keep these messages clearly recognizable and secure.

Does ZEPIC's Team Inbox show the OTP code to my agents?

No. ZEPIC masks the OTP in the Team Inbox, so agents can confirm a code was sent without ever seeing the code itself, keeping verification codes out of reach of anyone who doesn't need them.

What is the Copy Code button?

It's a button attached to the authentication message that lets customers copy the OTP to their clipboard, instead of manually reading and retyping it.

Does sending authentication messages cost extra?

Authentication messages are billed under Meta's Authentication conversation pricing, which is separate from marketing and utility conversation rates.

Can I include marketing content in an authentication message?

No. Authentication templates are restricted to verification-code content only. Promotional content needs to go through marketing or utility templates instead.

Is there a limit to how many authentication templates I can have?

You can create multiple, but we recommend one dedicated template per use case (login, reset, payment confirmation, etc.) to keep tracking and analytics clean.
