Answer

Previous Question Next Question

To securely store user passwords, use strong hashing algorithms and implement additional security measures to protect against unauthorized access.

<!-- 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 strong, adaptive hashing algorithm like bcrypt, Argon2, or PBKDF2 for password hashing.
Never store plain text passwords or use weak hashing algorithms like MD5 or SHA1.
Implement a password policy that enforces complexity and length requirements.
Consider using a pepper (a secret key stored separately) in addition to hashing for added security.
