While SMS OTP remains a highly effective and reliable standard for routine registrations, logins, and daily verifications, evolving global regulations and high-sensitivity transactions - such as fund transfers, password resets, and account recovery - now increasingly require an additional layer of security. To fill this gap without disrupting existing setups, EngageLab introduces Silent Auth. Silent Auth is not designed to replace SMS OTP, but to complete what OTP cannot cover alone in high-stakes scenarios. Utilizing Carrier Direct Connection, this solution seamlessly verifies the match between the user's phone number, SIM card, and device (MobileID) in the background within milliseconds. EngageLab Silent Auth is now available across 36 countries on 5 continents, enabling users to complete identity verification with zero input. Not only does this frictionless experience boost registration and login conversions by an average of 20-30%, but its end-to-end hashed data transmission strictly aligns with global privacy and financial regulations, such as CCPA and regional banking mandates like BSP Circular 1213. <img alt="Users simply enter their phone number to complete identity verification via direct carrier networks in just 2-3 seconds." height="277" src="https://ml.globenewswire.com/Resource/Download/331a66a1-27a2-40b8-9342-bc69c9ce1b06/picture-1-4494201.jpg" width="554" data-dpi="96" data-caption="Users simply enter their phone number to complete identity verification via direct carrier networks in just 2-3 seconds." data-filename="Picture 1 4494201.jpg" /> Silent Auth provides a more dependable approach to phone-based authentication across three key use cases: <ul><li>Faster Registration and Login: By removing SMS verification steps, the platform confirms user identity through carrier network authentication, reducing drop-off caused by SMS delays and significantly improving first-step conversion rates. </li><li>Secure Verification for High-Risk Operations: During sensitive actions such as transfers or password changes, the system provides real-time SIM Swap Detection to validate the relationship between the phone number and its active SIM. This ensures critical operations are initiated by the real account owner, reducing financial risks and Account Takeover (ATO) fraud without adding extra steps. </li><li>Marketing Fraud Prevention: During registration or campaign participation, the carrier network verifies the authenticity of the mobile number to confirm real SIM users, effectively blocking virtual numbers, emulators, and automated scripts to protect marketing budgets and ROI. </li></ul> Importantly, Silent Auth runs alongside businesses' existing OTP infrastructure. It verifies most users silently, and for anyone it cannot reach, the system seamlessly utilizes SMS OTP as an automated Fallback Channel. Together, this "Silent Auth + OTP" synergy ensures near-100% verification coverage. Businesses can upgrade their security seamlessly - no migration, no risk, just a powerful compliance and user experience upgrade right where it is needed most. In the wave of global expansion, seamless user experience and strict security compliance should not be a trade-off. The launch of Silent Auth not only enriches EngageLab’s omnichannel customer engagement portfolio but also reinforces Aurora Mobile’s commitment to providing global enterprises with stable, efficient, and intelligent solutions. Looking ahead, EngageLab will continue to leverage advanced technologies to help businesses build stronger, trust-based customer relationships and accelerate global growth.
