Previous Question Next Question

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 password database is compromised, the actual 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 well-tested library like bcrypt, Argon2, or PBKDF2 for hashing passwords.
Never store plain text passwords or use reversible encryption.
Regularly update your hashing algorithm to keep up with advancements in computing power.
