Security issues using WordPress!! Headache?? Don’t agitate, here’s easy two-factor authentication to make your WordPress log-in safe.

More often than not, all our passwords across various websites are one and the same – easy to remember, easy to hack! WordPress is namely, one of those sites! So why consider using WordPress Two-Factor Authentication Plugins, when WordPress already has one-factor authentication?

Well, read on.

What is Two-Factor Authentication?

What is Two-Factor Authentication

Two-Factor Authentication (2FA) is a method that confirms whether or not a user is legit, by combining two different, unrelated components. Usually, the two components are:

  • Knowledge – something that a user must know, i.e. PIN number or a password
  • Possession – something that a user must have, i.e. an OTP sent to another device, a security key or token

Previously, users could log in with the help of their knowledge, however, weak or repetitive passwords made it easier for hackers to attain sensitive information. Therefore, combining the two components (knowledge and possession) was thought of, because it was highly unlikely that the hacker could attain the password of a user along with the users’ possession.

WordPress Two-Factor Authentication

WordPress allows users to log in through one-factor authentication i.e. via passwords. A user can increase their website’s security by installing a plugin, which gives them the two-factor authentication feature. There are several plugins widely available and can be found in the plugin tab on the WordPress Dashboard. On installing a plugin, a user needs to activate it and follow the instructions that are prompted. It’s an easy procedure offering a better chance at security.

Why move from One-Factor to Two-Factor Authentication?

Although one-factor authentication is easy to use and saves time, it isn’t as secure anymore. 2FA’s basis lies in the fact that it is unlikely for a hacker to have two factors required for accessing an account. Passwords with varying strengths, symbols and characters along with generic security questions, have become pointless since they can easily be accessed. However, in 2FA, if an authentication attempt fails in even one instance, the account remains locked as access to the user isn’t granted. 2FA provides additional security and therefore many government and banking services have made the move from 1FA to 2FA.
