Two-factor authentication - what is it?
Die Two-factor authentication You can use for user accounts and protect them twice by entering an additional code in addition to your password.
How does 2-factor authentication work?
2-factor authentication means logging in using two factors to double protect an account, for example.
With the Authenticate password You are the owner of the account with second factor authenticated You the device as an authorized user. Since the email address is often not secret and the password can be intercepted, the 2-factor authentication (2FA) useful to protect your account.
Den second factor Should you generate on another device than on where you want to log in. That can a Numerical code in the form of TAN or one OTP be. Entering the password does not redirect you to your account, but to another barrier. You then enter the one-time password. If your login details have been hacked, the second factor protects your data as it can't be easily intercepted. Hackers are therefore trying to crack the authentication apps' algorithm.
The second factor
Well-known examples of 2FA are Online banking, which has been dealing with TANs that confirm transfers for a long time. The transaction number verifies that you have placed the transfer order. Another known process is also the EC card with chip, who identifies you as a legal owner, in addition to which you have the PIN for confirmation enter. Here they will Resources ownership and knowledge combined.
One-time passwords or one-time passwords (OTP) Perhaps you are more familiar with your email account or Instagram account (or your FreightPilot account ;)) to protect. These work pseudo-randombecause a algorithm creates it according to a pattern that users are generally not aware of and therefore appears randomly. If they're generated from an app, they have a watch and receive a timestamp, through which the verification ultimately takes place. That is why they are only valid for a short time.
