The best approach for storing passwords securely is:

  • Hash the password using a strong hashing algorithm like bcrypt.
  • Salt the password before hashing it. Salting adds a random string to the password, making it more secure against dictionary and rainbow table attacks. Example using bcrypt:
const bcrypt = require('bcrypt');
const saltRounds = 10;
bcrypt.hash('password123', saltRounds, function(err, hash) {
 // Store the hashed password in the database
});

Never store plain-text passwords. Always hash and salt passwords before saving them.
