About

SecondFactor is a cloud service for generating, sending, and verifying one-time passcodes (OTPs) for account sign-up, login, and other phone-verification workflows. Product and engineering teams integrate it through an API and SDKs for Kotlin, Swift, Dart, TypeScript, and server-side development, then manage authentication templates from a dashboard. For each OTP, its Price Intelligence Engine selects the lowest-cost eligible channel based on destination pricing and recipient eligibility. If delivery is not confirmed within eight seconds, automatic fallback tries the next eligible channel. SecondFactor supports SMS, WhatsApp, Viber, and RCS, subject to destination, recipient, and account setup. Delivery logs show the destination, channel, status, and cost for each request. The service handles OTP generation, delivery, and verification so teams can add phone verification to their applications and manage delivery across multiple channels and markets.

About

Tambua is a developer-focused one-time password (OTP) verification API for applications serving users in African markets. Applications request a code and verify it through API calls, with delivery by SMS, WhatsApp, voice, email or M-PESA. Ordered channel fallback can route a code through another channel when delivery fails or times out. The service uses shared sender IDs and provides per-country pricing, signed webhooks, request logs, free test keys and a Node.js SDK. Developers can add verification to account sign-up, login and transaction-confirmation flows in fintech, e-commerce, gaming, logistics and other mobile or web applications. The API is intended for teams that need to verify phone numbers or confirm sensitive actions across African markets; channel availability and charges can vary by destination.
