How can I securely store user passwords in my application?

Asked on Nov 25, 2025

Answer

To securely store user passwords in your application, you should use a strong, one-way hashing algorithm with a unique salt for each password. This ensures that even if the password database is compromised, the actual passwords remain protected.

<!-- BEGIN COPY / PASTE -->
    const bcrypt = require('bcrypt');
    const saltRounds = 12;

    function hashPassword(password) {
      return bcrypt.hash(password, saltRounds);
    }
    <!-- END COPY / PASTE -->

Additional Comment:

Use a well-established library like bcrypt, Argon2, or PBKDF2 for hashing passwords.
Ensure that the salt is unique for each password to prevent rainbow table attacks.
Regularly update your hashing algorithm to the latest standards to maintain security.
