How to Securely Store User Passwords on a Website

Why Password Storage Matters

The security of your business website depends on how you handle sensitive information. Never store passwords in plain text within your database. Even in the event of a data breach, attackers should not gain access to actual user credentials.

Use Robust Hashing Algorithms

Instead of outdated methods like MD5 or SHA1, utilize modern key derivation functions designed to be slow and resistant to brute-force attacks. Suitable choices include:

• bcrypt: An industry standard that automatically incorporates "salting".
• Argon2: The winner of the password hashing competition, known for its high protection level.
• scrypt: Specifically designed to require a significant amount of memory, hindering hardware-accelerated attacks.

The Role of Salting

Always add a unique, random value, known as a "salt," to every password before hashing it. This ensures that even if two users choose the same password, their stored hashes will look completely different. This prevents the use of "rainbow tables" to reverse-engineer passwords.

Practical Implementation Steps

1. Use the built-in cryptographic libraries of your chosen programming language.
2. Configure the "cost factor" to make the hashing process sufficiently slow while maintaining server performance.
