What is two-step verification and what is this security tool for?

Two-step verification is a security measure that extends the level of protection to access different computer applications. When using this tool, the user must not only enter a phrase or word, a pattern, fingerprint or facial recognition to access the app, you must also enter a 4-6 digit PIN as an additional measure of identity detection.

This number can be fixed or vary with each access attempt (for the latter, it is usually received by SMS). Therefore, this type of protection prevents intruders from being able to easily access the platforms, even if they know the password.

How does double factor verification work on the Internet?

The operation of the two-factor verification is very simple. When you download an app You must register by entering your email and an access password, so every time you want to access this app you will have to write the password that you chose when registering as a user.

When you add a two-step verification, what you are doing is configuring the platform so that it asks you every time you enter it for your registration password and then a code that you must write each time you access.

Therefore, you will have to prove twice that you are the legitimate user. In some apps, this access PIN varies constantly and it is received through the same application, from an SMS or an email (This mechanism is used a lot in banking platforms). You can also choose that every certain period you must enter the same PIN, this is the case of, for example, WhatsApp.
