Do I need 2FA?

Without a doubt – needed! Although they have not yet come up with a method that would work without failures and protect data 100%, the inclusion of two-factor verification will significantly protect against the leak of personal data, financial losses, or theft of information.

Two-factor authentication is useful for business for several reasons:

• Increasing the confidentiality of business information;
• Protection of personal data of employees;
• The probability of hacking and loss of any company data is reduced;
• Allows verification of users without difficulty;
• Registration in applications does not take more than 2 minutes.

There are three main types of verification: via SMS messages, voice calls and email confirmation.

In the first case, the client receives a one-time code (OTP) on the phone after entering his password.

GSM offers voice verification. In this case, a call is made to a fixed subscriber number, where the last 4 digits of the incoming call number are important. Authentication occurs from random numbers, so it’s impossible to guess the numbers.

Today, verification via email is practically not relevant, since privacy is much lower than in the previous two options.
