One API. Every channel, picked for you.
Stop hard-coding fallbacks. Mobile Auth reads operator health, country, and device state — then picks the channel that's actually working right now. SNA, WhatsApp, SMS, Voice. We pick. You ship.
Every login is a decision. We make it for you.
Mobile Auth reads signals — country, carrier, SIM, device, channel health — and picks the method most likely to log this user in, fastest.
The channel pool, in detail.
Four channels. No hierarchy. Mobile Auth picks the best one per request — but here's what each does, and when it wins.
Mobile Auth gets smarter with every request.
Every login feeds back into the optimizer. Per-route, per-carrier, per-hour success rates and latencies update continuously.
When a provider degrades, traffic shifts before you even notice. When a new pattern works, it's the new default.

One call. Every channel routed for you.
You don't pick channels. You don't write retries. You don't wire fallback. Mobile Auth makes the decision and returns a verified token.
import com.otpless.main.OtplessManager import com.otpless.dto.HeadlessRequest import com.otpless.dto.HeadlessResponse // 1. Init the OTPLESS view in your sign-in activity private val otplessView = OtplessManager .getInstance().getOtplessView(this) // 2. Build the verify request — just a phone number val request = HeadlessRequest() request.setPhoneNumber("91", "7069914791") // 3.
