Protecting your WordPress site is obviously important. There are plenty of precautions you can take to avoid getting hacked and having your site compromised. One of the best forms of protection is two-factor authentication.
If you manage a WordPress site or even several sites for clients, beefing up the overall security of a site is a no-brainer. Most users know how to strengthen passwords, but two-factor authentication takes security to the next level.
Even if a hacker guesses your username and password, they will not be able to login to your site without a code, which is usually connected to your smartphone or emailed.
We’ll look at six authentication plugins available for WordPress. Most are highly rated, free, and can offer a great solution to stopping hackers in their tracks.
Our very own answer to security, Defender, features two-factor authentication that can be customized to your specifications to keep your site secure.
The 2FA works in collaboration with the Google Authenticator app, making it easy to use. There is also a Lost Phone feature so that users can get an OTP (one-time-pass) code sent to their email.
You can also select user roles for whom 2FA should be enacted. Plus, as an additional option, you can enter a custom message that will be shown to the user if they have not yet enabled it.
Some of Defender’s main features for 2FA are:
- Enable two-factor authentication for specific users
