Improve password security with the Better Password Hash of WPMasterToolKit

Password security is a critical issue for any WordPress site. With brute-force attacks and database leaks becoming more and more frequent, it's becoming essential to use modern, robust hash algorithms. To meet this need, we've developed the Better Password Hash in WPMasterToolKit. Its aim is simple: to improve the WordPress password hashing algorithm by using Argon2idone of the safest standards currently available.

Which plugin can Better Password Hash replace?

Better Password Hash can replace some security plugins such as :

• WP Password Argon2
• WP Enhanced Password Hashing
• And any other plugin designed solely to improve password hashing, without any additional features.

This allows you to reduce the number of active plugins, limit potential conflicts and optimize your site's overall performance.

Why use Argon2id for password hashing?

Argon2id is a modern algorithm that won the Password Hashing Competition in 2015. It is designed to :

• Resist GPU (graphics card) attacks
• Takes available memory into account (making it highly effective at slowing down brute-force attacks)
• Adapts to hardware upgrades (easier to configure than bcrypt)

With Better Password Hash, if your server supports Argon2id, WordPress automatically switches from bcrypt (the default algorithm) to Argon2id.

How does the Better Password Hash module work?

Once activated, the module will :

1. Check whether your server supports Argon2id with the function password_algos().
2. If available, it forces WordPress to use Argon2id via the filter wp_hash_password_algorithm.
3. If Argon2id is not available, it lets WordPress use bcrypt as usual.
4. At the same time, it displays a notification in the admin dashboard to let you know if Argon2id is not activated on your server.

How to use this module

It's extremely easy to use:

• Activate the Better Password Hash in the WPMasterToolKit control panel.
• If your server supports Argon2id, the module will activate it automatically.
• If your server doesn't support it, a warning message will appear in the admin interface prompting you to update PHP or adjust the server configuration.

No additional configuration required!

Our technical choices

We've chosen to use the WordPress hook wp_hash_password_algorithm to ensure maximum compatibility with the WordPress core. This means we don't touch the login system or database directly: we simply improve the underlying algorithm.

On the detection side, we use :

• password_algos() to detect available algorithms
• PASSWORD_ARGON2ID to verify the specific presence of Argon2id

Finally, we have integrated a admin_notices to inform site administrators in the event of incompatibility, to guarantee total transparency.

Conclusion

The module Better Password Hash from WPMasterToolKit is a simple yet powerful solution for strengthening password security on your WordPress site. By using Argon2id, you get state-of-the-art protection with no extra effort. Just activate it, and let it do its job discreetly!
