OTP FAQ

Find out what are the frequently asked questions about the OTP service.

OTP significa One-Time Password. Es una contraseña temporal asociada a un destino que solo puede validarse una vez y deja de ser válida cuando caduca o se verifica correctamente.

OTP es un tipo de código de un solo uso. 2FA es un método de acceso con dos factores distintos; un OTP puede utilizarse como segundo factor, pero también para verificar un alta o una transacción.

Se usan para verificar teléfonos, activar cuentas, recuperar contraseñas, confirmar pagos o cambios sensibles y validar entregas, pedidos o reservas.

Puedes combinar la API OTP con los canales compatibles de Afilnet, como SMS y voz. La disponibilidad, la cobertura y el coste dependen del canal y del destino.

Our platform allows you to generate codes with any length of characters and any format (including letters, numbers or special characters), your company can choose the format of its OTP codes.

Tu software solicita la generación del código, lo entrega mediante el canal elegido, recoge la respuesta del usuario y llama a la verificación antes de completar el proceso.

The use of the OTP service for the generation and verification of codes is free. In Afilnet you will only have to pay for the use you make of the channels to send the generated codes.

Además de utilizar una vigencia corta, conviene limitar intentos, solicitudes y reenvíos, evitar registrar el código y proteger los procesos alternativos de recuperación.
