9 Best PHP Password Libraries

Here are the best open-source PHP password libraries for your applications. You can use these to enable secure password storage and management functionality in PHP-based applications.

These libraries provide an essential layer of security to PHP applications by ensuring that user passwords are properly encrypted and protected from potential attackers. The PHP Password libraries offer a range of password hashing algorithms and functions to help developers protect the user's passwords against unauthorized access and data breaches. These Libraries support various hashing algorithms such as bcrypt, scrypt, Argon2, and PBKDF2 and provide a built-in mechanism for generating strong, random passwords. The PHP Password Hashing API provides a simple, secure, easy-to-use password hashing mechanism. Moreover, developers can customize the password hashing process according to their needs. Along with that, you get a variety of features for enforcing password policies, such as:

• Password validation
• Password generation
• Maximum password age
• Minimum password length
• Password strength estimation 
• Password complexity requirements

Overall, PHP password libraries help developers build more secure and reliable applications. Also, you can provide peace of mind to users who entrust their personal information to online services.
