5. Implement 2-factor Authentication

Implementing Two-Factor Authentication (2FA) is a robust security measure to protect your WordPress site from unauthorized access. It adds an additional layer of security beyond just a username and password. Even if a bot or malicious user manages to obtain login credentials, they won’t be able to access the site without the second authentication factor. To implement 2FA in WordPress, you can use the “Two-Factor Authentication” plugin.

Two-Factor Authentication (2FA) in WordPress:

Two-Factor Authentication (2FA) is a security method that requires users to provide two different authentication factors to verify their identity. These factors typically fall into three categories:

1. Something You Know: This is the traditional password, PIN, or passphrase that the user knows.
2. Something You Have: This involves a physical device, often a smartphone, token, or smart card, which generates a one-time code or acts as a secondary key.
3. Something You Are: This encompasses biometric data like fingerprints or retina scans, which are unique to the user.

The “Two-Factor Authentication” Plugin:

To enable 2FA in WordPress, you can use the “Two-Factor Authentication” plugin. This plugin enhances your site’s security by requiring users to provide that second authentication factor before they can log in. It provides several authentication options, including:

• Time-based One-Time Passwords (TOTP): Users generate one-time codes using apps like Google Authenticator or Authy.
• Email Codes: Users receive a one-time code via email.
• FIDO Universal 2nd Factor (U2F): Users employ physical U2F devices like YubiKeys.
• Duo Security: Users receive push notifications on their mobile devices and can approve or deny login attempts.

6. Adding a Robots.txt File in WordPress:

A Robots.txt file is a powerful tool to guide legitimate search engine bots and web crawlers about what parts of your website they can access and what they should avoid. It is a plain text file that instructs web robots (also known as “bots” or “crawlers”) on how to interact with your website’s content. By using a Robots.txt file, you can optimize your site’s crawlability, safeguard sensitive information, and improve SEO. To add a Robots.txt file to your WordPress website, you can follow these steps and use the “Virtual Robots.txt” plugin:

Plugin: Virtual Robots.txt:

• Virtual Robots.txt: This WordPress plugin allows you to generate, edit, and manage your Robots.txt file directly from your admin dashboard. It simplifies the task for users who may not be comfortable accessing their site’s root directory and manually creating the file.
