In recent years there has been an exponential increase in cases of fraud and computer attacks and security in any computer system or software is a crucial issue.

Therefore, it is necessary to increase cybersecurity measures by companies and organizations in order to guarantee the protection of end-user services and thus improve the trust and reliability of the service.

Previously, only financial institutions had two-factor or multi-factor authentication, but now it has spread to more sectors and can be found in many access, registration or authentication processes.

In times of constant cyber-attacks and cybercrime, OTP codes and 2FA processes provide a necessary and essential security to any system and confidence to users.

In this sense, LabsMobile provides the SMS channel which, thanks to its characteristics, is ideal for this type of processes. SMS messages can be automated (with a platform like LabsMobile), delivered in a few seconds and are compatible with any mobile device and person around the world without the need for any installation or configuration.

In fact, a large percentage of SMS messages sent today are OTP codes for validation, verification or authentication processes.

What is an SMS OTP Code?

In order to create a secure and reliable authentication or validation process, one of the most effective and widespread techniques is the multiple or double factor authentication (2FA - Two Factor Authentication) by means of an OTP code. This code is generated right after entering the credentials (username and password).

Therefore, an OTP (One Time Password) code is a random code or password generated specifically for a registration, validation or access process.

OTP codes can be used in a multitude of actions and processes such as:

  • - Two-factor or multi-factor authentications.
  • - Verifications of a cell phone and association to a user.
  • - Signature of documents.
  • - Voting and participatory processes.
  • - Access codes to online portals.
  • - Confirmation of payments or economic transactions.
  • - Physical access: opening doors, WiFi connections, rental/share car access...
  • - Personalized discount codes.

In addition, OTP codes can be transmitted through different communication channels, but sending them via SMS is one of the most widely used. Particularly because it adds security as it is sent over a channel that is difficult to intercept such as the GSM network.

What will we achieve with the OTP verification code?

Generate greater security and reliability in any system or environment and thus prevent any unauthorized access. In fact, even if it is leaked or a third party possesses the password it will not manage to finish the validation process (registration, access or verification).

How does it work an SMS OTP Code?

The standard process is that the user must enter in a web or app environment the code received in order to successfully complete the validation. To do this, usually only one code is sent per validation process and this has a temporality of between 5 and 30 minutes for security reasons.

An OTP code by SMS is sent through the GSM network, which is more reliable and secure since it is not transmitted over the Internet and is much more difficult to intercept.

To make use of these SMS messages with OTP codes, the standard API or LabsMobile OTP API must be automatically integrated.

It should be noted that many mobile devices have automatic functionality where the code received in the last seconds appears and allows copying it directly into the application / verification page. This allows an improvement and facilitates usability.

How much does it cost an SMS OTP Code?

The OTP code sending service has no additional cost, as in most LabsMobile services you only pay for the SMS messages sent.

In any case, in order to calculate the cost of this service we recommend taking into account how the price of SMS messages is calculated and different factors of user behavior such as: different access attempts, alternative channels (email, call, etc.), destination country, etc.
