"<p>In this tutorial, we’re setting up secure user registration in our Node.js API by focusing on password hashing with bcrypt. Password security is crucial in any app, and bcrypt helps us protect user data by making stored passwords unreadable to anyone who might access our database.</p> <p>When we’re building a registration system, a key priority is making sure our users' passwords are secure. Storing passwords as plain text is risky because if our database is ever compromised, those passwords are exposed. By hashing passwords, we’re transforming them into unique, unreadable strings that are practically impossible to reverse. This way, even if someone accesses our database, they can’t see the actual passwords.</p> <p>We’re using bcrypt, a trusted tool for password hashing in Node.js. Bcrypt goes beyond simple hashing by adding a “salt” a bit of random data, to each password before it’s hashed. This ensures that even if two users choose the same password, the resulting hashes look completely different, providing a strong defense against brute-force attacks. With bcrypt, we’re taking a proactive step to keep our users’ data safe and secure, building a solid foundation for our application’s security.</p>"
