Second-factor verification you do not have to build.
Writing your own OTP layer looks like an afternoon of work and turns into a quarter of maintenance. Code generation, expiry, retry limits, the race when a user requests a second code before the first expires, the abuse case where somebody loops your endpoint to bomb a stranger's phone, and a storage decision that a security reviewer will eventually ask you about. All of it is undifferentiated work that every product rebuilds identically.
With the 2FA API you call send with a number, and call verify with whatever the user typed. The code itself lives on our side with its expiry and attempt counter, so there is no secret in your database to leak and nothing to compare in your own code. If you would rather generate codes yourself, you still can — use the OTP SMS route directly and keep the logic in-house.
- Send and verify endpoints — no OTP storage or comparison in your codebase.
- Configurable code length, expiry and maximum attempts per application.
- Multi-channel — the same code can go by SMS, voice call or WhatsApp.
- Rate limiting and abuse protection to stop OTP-bombing of your users.
- Audit log of every issue and verify event, exportable for compliance review.
