Sinch for Web

Boost Your App’s Features and Protection

Sinch offers a set of communication tools—voice, messaging, verification and video—used by many modern technology companies. Integrating Sinch lets an app add voice calling and SMS-driven two-factor authentication quickly, improving both user functionality and account security.

Core Communication Capabilities

• HD video calls for real‑time visual interaction
• SMS messaging for notifications, alerts, and OTPs
• VoIP (Voice over Internet Protocol) for in‑app voice calling
• Phone number verification and two‑factor authentication services

Enhancing Security

Sinch supports stronger authentication methods in addition to standard SMS codes. One example is Flash Call technology, which verifies a user’s number by checking an automated incoming call rather than relying solely on SMS messages. These options reduce fraud risk and can streamline the verification flow for end users.

Why It Helps Apps Grow

By providing global voice, messaging and verification infrastructure, Sinch enables apps to reach a wider audience across countries and networks without building complex telephony systems from scratch. This reduces development overhead while delivering reliable, scalable communication features.
