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

TringPhone is a browser-based international calling service for individuals and teams contacting mobile phones and landlines abroad. Users check destination-specific rates, add prepaid credit, enter a full international number, and place calls in Chrome, Safari, Firefox, or Edge with microphone access. The recipient answers on a regular phone and needs no TringPhone account or app. Calls are pay as you go; rates vary by destination and whether the number is mobile or landline, and partial minutes are rounded up. Personal top-ups start at $5. Business accounts can invite team members and organize calling credit. Optional virtual phone numbers are offered separately, with availability and recurring charges varying by country. TringPhone supports personal conversations and business calls to overseas contacts, including people who cannot or do not use internet calling apps.
