Switch to HTTPS from HTTP

The SSL / TLS certificate is important because it ensures the security of your website. Google prefers to rank websites with SSL over those without.

What is HTTPS?


HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP. This is a protocol through which data is sent between the web browser and the website that you are connected to. “S” after HTTP refers to “Secure” meaning the communication between a web browser and the website you are browsing is encrypted.

Websites without SSL certificates become easy targets for hackers. HTTPS is the safest version of HTTP, so be sure to use HTPPS. Most of the quality hosting services offer SSL certificates for free.

Use Strong Login Credentials

In WordPress, everyone knows the path to the login page. Therefore, it is so important that you keep your login credentials secure. Never use your name as a password, since it is easy to guess. And do not use your domain name as a username, because a hacker can easily guess it. 

We strongly recommend you change the default login information and select strong passwords that are difficult for people to guess. Apart from that, you can also do the following tasks to harden WordPress security.

  • Change Login URL: As all WordPress websites have the same login page by default (http://www.example.com/wp-login.php), it is easy for hackers to guess and run a brute-force attack. Changing the WordPress site’s login page URL is a smart way to protect your site from hacking attempts. We have a tutorial on how to change the WordPress login URL. follow this tutorial and add an extra level of security to your WordPress site.
  • Change the Default “admin” Username: Leave no option for the hackers to guess your username. Change your default username and make it anything but admin or anything easy to guess. 
  • Limit Login Attempt: WordPress lets users try to log in as many times as they want. This makes your WordPress site vulnerable to brute-force attacks. Hackers try to crack passwords by trying different combinations. In this case, you should limit the login attempt and secure the WordPress site.

  • Change your Password Often: Change your WordPress site password regularly. It is one of the WordPress security best practices. Make sure you never set a weak password for your site.

Enable Two-factor Authentication

Two-factor authentication refers to a two-way process through which an admin has to go to log in. This process takes a little longer but makes your WordPress site more secure.

First, you enter your username and password. Then a unique code will be sent to your device or email that you need to provide to the system, and only after that, you can enter the admin panel of the site. You can add this system using a two-factor authentication WordPress plugin. It ensures the greater security of your website. Two-factor authentication is one of the major steps to secure a WordPress site. Be sure to have it on your WordPress security checklist.

Keep Track of Users’ Activities on Your Site

Keeping track of all the users’ activities on your site is another way to harden website security. It helps you detect suspicious behavior and thwart malicious attacks. Always be on alert and take action before anything terrible happens to your site.

If you can record all the necessary user activities such as login, content publishing and changes, plugins, themes, and WordPress settings changes, and failed login attempts with source IP addresses, you can spot the threat and take action quickly.

You can install WP Activity Log (formerly WP Security Audit Log) to record all these user behaviors. It also eases troubleshooting and detects any suspicious behavior before it poses any security threat to your site.

Carefully Select Plugins and Themes

Themes and plugins are the best that WordPress provides, but be sure to add proven high-quality software products. It is important that the site from which you download looks good, but do not use plugins or themes from any site. Most hackers make site download themes quite attractive. They rub into your trust, and then, through the malicious programs that you downloaded from them yourself, hack into your websites.

Carefully Select Plugins and Themes

On the other hand, check user ratings and comments before loading plugins. You can also check out how developers update themes and plugins. If the plugin has not been updated for 6 months or a year, do not use it. Download themes and plugins from trusted sources such as WordPress, ThemeForest, and other well-known websites.

WordPress is a well-known platform, and when websites become famous, many people are ready to destroy them. That is why many websites are hacked: someone does not want to see your products on top. Therefore, if you spend money and time on a website, use these techniques and make your WordPress website as secure as possible. Selecting plugins and themes carefully is one of the WordPress security best practices.

Use WordPress Security Plugins to Strengthen Security
