Previous Question Next Question

To securely store user passwords in a web application, use a strong 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 = 10;

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

Additional Comment:

Always use a well-established hashing library like bcrypt, Argon2, or PBKDF2.
Never store passwords in plain text or use reversible encryption.
Regularly update your hashing algorithm to keep up with security advancements.
