Frequently Asked Questions
1. What is SMS-based 2FA and how does it work?
La 2FA (autenticación de dos factores) basada en SMS utiliza un contraseña de un solo uso (OTP) enviado por SMS para verificar la identidad de un usuario. Cuando un cliente inicia sesión o realiza un pago, nuestro API de verificación OTP genera y entrega instantáneamente un código, lo que garantiza un acceso seguro en cuestión de segundos.
2. Can I use WhatsApp OTP for two-factor authentication?
Yes. Message Central offers WhatsApp Business API for OTP delivery. If SMS fails due to network issues, OTPs automatically fall back to WhatsApp, ensuring 100% delivery. This makes 2FA both secure and user-friendly.
