From Zero to Auth: Flask-Login for Beginners
What happens when you try to add login and registration to your Flask app?
Well… the routes did start working.
But did my soul? Also, not so much.
In this relatively chill crash course, I’ll take you through:
🧠 How to wire up Flask-Login and protect routes
🔐 Setting up a user model with hashed passwords (no plain text, please)
🧾 Building registration and login endpoints + form flow
🛡️ Using @login_required to guard your dashboard and logout logic
⚙️ A few small tweaks (secret key, user loader) to make it actually usable
Whether you’re just trying to get your Flask app off the ground or tired of seeing “Please log in” everywhere — this one’s for you.
👇 Challenge: try adding “forgot password” logic or email verification and post your version in the comments!
