Truecaller 1-Tap Login

Enable 1-tap phone number verification with Truecaller. Nativine embeds native Truecaller SDKs, allowing users in India and global markets to verify their phone numbers instantly without entering manual SMS OTP codes.

Truecaller is the dominant phone verification method in South Asia and emerging markets. Nativine's native Truecaller bridge presents a 1-tap verification dialog overlaying your web application:

• Zero-OTP Instant Login: Users tap "Continue as [Name]" to instantly verify their mobile number without waiting for SMS OTP delivery.
• Pre-Filled Profile Metadata: Automatically receives verified user name, phone number, email, and location.
• Fall-back OTP Bridge: Automatically triggers standard SMS OTP verification if the user does not have the Truecaller app installed.
