Enhancing Security with One Time Passwords (OTP)

Nowadays, security in digital transactions is essential, especially in the face of the threat of fraud or extraction of the passwords we use to access our bank account, email or even social networks. In this context, a second layer of validation is suggested as a practical and efficient tool to authenticate before authorizing a transaction.

Thus, One Time Passwords (OTP), alphanumeric sequences that function as a temporary code to be entered in the app or website, are an excellent cybersecurity alternative so that the end user can give a second identity confirmation signal. This method has become widespread, especially in banking or payment transactions, with various forms of delivery that can facilitate its use.

Meanwhile, how and where they are received by the user affects their effectiveness, since OTPs are often sent via email or SMS, but this requires proactive opening of the message by the user and an additional step such as copying and pasting the text. Identifying this room for improvement, WhatsApp has also transformed itself into a channel for receiving OTPs, incorporating interesting new features.

Key functionalities and benefits of OTPs implemented in WhatsApp:

  1. Automation: instantaneous reception and limited validity
    • OTPs are instantly generated and delivered to the customer’s WhatsApp account, ensuring a seamless user experience.
    • Its limited validity adds an additional layer of security, ensuring that the code is only valid for a specific period of time, thus reducing the risk of unauthorized access.
  2. Protection: secure shipping and 24×7 availability
    • OTPs are sent securely, using WhatsApp’s encrypted channel option to protect sensitive information during transmission.
    • Customers can receive codes automatically, at any time, providing an immediate response to authentication needs.
  3. Simplified: direct reading and option
    • The OTPs are presented in a clear and straightforward manner for easy and effortless reading, including a button to copy the OTP.
    • Even if the target application of the OTP is on the same device, an automatic match is generated to speed up its use.

Sending One Time Passwords via WhatsApp not only ensures information security, but also provides a convenient and accessible experience for users. WhatsApp is a widely used and trusted platform, which means that messages are delivered quickly. In addition, WhatsApp’s interface makes it easy to read and enter codes, providing a hassle-free experience for your customers.


How can you incorporate this additional layer of security effectively for your users? The answer lies in the combination of advanced technologies. Through our mass and personalized messaging solution, “Reach & Engage”, together with Meta’s Authentication Template and integration with your CRM/ERP systems, you can unlock the full potential of OTPs. This integration ensures a frictionless and efficient implementation, enhancing security without compromising your users’ experience.
