Sub-3 Second Instant OTP Delivery SLA for Authentication, Mobile Login & 2FA.
One-Time Passwords (OTPs) are critical for user login, two-factor authentication (2FA), banking transactions, and security checks. A delay of even a few seconds can result in user drop-off and lost revenue.
OTP LCD provides dedicated high-priority OTP pipes connected directly to primary Indian telecom operators (Airtel, Vi, Jio, BSNL) ensuring sub-3 second delivery latency across India.
