FAQ

Questions

What is the difference between OTP and 2FA?

An OTP is a single-use passcode; 2FA uses that passcode as a second factor on top of a password.

How reliable is delivery?

Sent over an optimized global network, with real-time delivery tracking.

Can I integrate OTP with my existing system?

Yes — a REST API and multi-language SDKs connect to your app, CRM or website.

Is the delivery secure?

Protected with end-to-end encryption, aligned with international standards.

Which channels can carry the code?

Codes can be delivered by SMS, with voice as a fallback when a text can't get through.

Can I use my own sender ID or template?

Yes — sender IDs and message templates can be configured, subject to local registration requirements in some markets.

What content can’t be sent?

We operate strictly within each market’s regulations: unlawful or restricted content isn’t accepted, Sender IDs are registered per local rules, and opt-out requests are honoured automatically.
