PHP remains the most popular server-side programming language: it is used by almost 80% of websites (source). This language continues to be developed, and PHP 8 was released last week ! This version brings new features and should enhance security.

However, the security of PHP builds up from its ‘historical’ core features. The following article does not replace a good knowledge of PHP, and there will be nothing to copy/paste directly into your files. But we believe that these tips and best practices will bring you long-term benefits if you understand and implement the different points according to your needs and context.

Today we cover PHP configuration, updates, code organisation and data filtering/escaping.

What is 2FA

Two Factor Authentication (2FA) is a way to strengthen users authentication.
A good example is when you want to trigger a bank transfer from your bank website: depending on your bank, you may receive a text message on your mobile phone, containing a code that you must put back on the website to confirm the transfer.

The second factor can be a phone, a physical object in your possession, some physical characteristic (biometrics) or a secret that only you know.

A 2FA process comes with some disadvantages: it makes the authentication process more complex, and the second factor has to be “available”, which can be a problem with a mobile. Flat battery, bad network coverage or any other hazard can prevent the process from working properly.
