2FA — simply explanation

Oye, that's a tricky word... Two f a! Give me a minute to simplify it 🧐

Authentication is logging into an account for a service like Google. Service check that logged person is you.

This process usually consists of entering two fields:

  • email or phone

  • password

what is 2fa

Fraudsters try to hack our passwords like fishing or password brute force.

Services are interested in our data security and provide extra protection. It’s one more secure layer called double authentication. How does it work, and how to set up?

It works as an extra code between the service and mobile generator. Almost all services use a proven application from Google: Google Authenticator. Links for installation on Android and iPhone & iPad.

Connecting is easy: the service will show you a QR code to be scanned by your phone, and that's it. So use double authentication at the first opportunity.

what is Google Authenticator

After all, every new login will ask 2FA pass, which you can find at Google Authenticator. So easy, so securely!

How check what service support 2FA? There is 2 way:

  • google “title of service 2FA”

  • check at page settings for an account

It's worth noting that some services like Facebook have their applications for generating such codes. The principle of their work is the same, the only inconvenience is that this code will not be with others in Google Authenticator.
