How Can I Create a Login and Registration Form for My Website?

Seriously, don't attempt to build your own authentication system! Always store passwords hashed, never in plain text. A good approach is to use a template with built-in authentication, like the one I found on GitHub: github.com/sahat/hackathon-starter. It handles the hard parts for you, and you can easily remove social logins if they're not needed.

At a fundamental level, you'll need three components to make this work: a frontend form for collecting email and password, a backend server to validate those credentials, and a database like PostgreSQL or MongoDB to store user information securely (always use hashed passwords!). For 'Sign in with Google', you should use OAuth to handle the authentication securely. If you're just getting started, practice with a basic email/password setup first before jumping into OAuth—it can get overwhelming. What backend technology are you using?

Authentication can be quite complex, especially if you’re new to it. I recommend checking out established solutions like Firebase Auth or Auth0. They make adding features like 'Sign in with Google' a breeze, and you'll avoid any pitfalls related to data security as you learn. Trust me, this stuff gets really tricky! It's great that you're considering security seriously, though!
