As answered by people managing GetResponse and SecondFactor.
SecondFactor's answer:
SecondFactor's answer:
The Intelligence Engine identifies the destination country and operator, checks which channels are available, and uses automatic routing to send the OTP over the lowest-cost eligible channel. If the delivery isn't confirmed within 8 seconds, automatic fallback moves to the next eligible channel.
SecondFactor's answer:
Your backend doesn't generate, store, or check the code itself. Instead, SecondFactor generates the code, picks the optimal channel, delivers the OTP and verifies it. If you are moving from another OTP provider, you keep a simple send-and-verify integration instead of rebuilding your verification workflow.
SecondFactor's answer:
SecondFactor is an OTP API for vibe-coders and product teams. It fits fintech, tech-enabled marketplaces, and international platforms that send OTPs to users in more than one country.
