How OTT & Push Authentication Works

One Authentication Request. Three Steps Before Access Is Granted.

OTT and push authentication delivers secure verification requests through digital channels, helping businesses authenticate users quickly while reducing login friction.

Authentication Request Is Triggered.

When a user starts authentication, SMSala sends a secure verification request through OTT or push channels connected to your application.

Step 2 — User Confirmation

User Identity Is Verified.

  • Reduced login friction
  • Improved account security
Verification Result Is Delivered.
Step 3 — Authentication Response

Once verification is completed, your application receives the authentication response through API integration and grants secure access.
