In connection with the increasing cases of "hijacking" of sites, their hacking, "awarding" with malicious software, the topic of increasing the level of security of an Internet project is becoming especially relevant. If it was previously considered a good measure to come up with complex, unpredictable passwords for accounts, now this may not be enough. If your resource contains information that is obviously interesting for fraudsters, then use two-factor authentication (2FA).
If you have only heard about this method, now is the time to get to know it better, nigeria whatsapp number database understand the principle of operation, and in what cases it can be used. This is what our article is dedicated to.
What is Two-Factor Authentication (2FA)
This is a method of recognizing the authenticity of a user, confirming their right to enter a service by using two different types of authentication information. In simple terms, this is a two-step identity verification during authorization, which makes account protection more reliable, significantly reducing the risk of unauthorized actions.
The application of two-factor authentication looks like this:
Step one – enter your login and password.
The second step is entering additional data (for example, a code from an email).
The principle of the scheme is simple: to get to the required resource, you need to confirm your identity twice with keys, one of which you remember, and the other came, for example, to a device that you own.
How Two-Factor Authentication Works
There are 2 types of two-factor authentication used:
Thanks to the internal procedure of the Internet platform, when a code is sent to the user's phone or email, which is necessary for entering into a specific line and logging into the account.
Using an application that works together with the resource. For example, a person installed Yandex.Key, thereby ensuring the availability of this platform's services, VK accounts. The tool is capable of reading QR codes, creating one-time passwords.
After the received code has been entered, the person gets the opportunity to enter the site. In case of loss of necessary codes, technical support can help restore access rights.
How difficult is it for scammers to “break through” two-factor authentication? The task will be easy if your mobile phone is in their hands and the code is sent via SMS. But if the code is sent to your email, it will be more difficult to get to it.
