What's the best way to securely store user passwords in a web application?

Asked on Dec 06, 2025

Answer

The best way to securely store user passwords in a web application is to use a strong, one-way hashing algorithm with a unique salt for each password. This ensures that even if the database is compromised, the passwords remain protected.

<!-- BEGIN COPY / PASTE -->
    const bcrypt = require('bcrypt');
    const saltRounds = 10;
    const password = "userPassword123";

    bcrypt.hash(password, saltRounds, function(err, hash) {
      // Store hash in your password DB.
    });
    <!-- END COPY / PASTE -->

Additional Comment:

Always use a reputable library like bcrypt, Argon2, or PBKDF2 for hashing passwords.
Never store passwords in plaintext or use reversible encryption.
Regularly update your hashing algorithm to the latest standards to maintain security.
