What is two-step authentication?

Two-step authentication is a service that offers a level of additional security that helps prevent unauthorized access to an account on a computer system.

To create this level of security, the user must have a mobile phone number or email, this will be used to receive a code that the user will include in the platform, once you have included the correct credentials of your account.

In this way we ensure that even if there is another person who has the credentials of this account, the legitimate user will be the only one who can access it through this authentication method

How does it work?

Two-step authentication is easy to use and integrate into your business processes, and will help you improve security. Two-step authentication has the following steps:

<b>Step 1.</b> The user insert his/her credentials
