Secure your Flask06.26.17 · python flask
Hey there, I still can’t you promise regular posts, but I am trying to write as often as I can!
Writing & deploying Flask apps is super fun. I love how easily it is to put together a dashboard, proof of concept hack, or even a full-blown app and get it online.
But, while I’m good about using environment variables & not committing my API keys to git, I don’t build a lot of security or user authentication into my apps. That’s because it requires a bunch of extensions, a database, callbacks, etc.
Most of my apps need a simple login/password, not a full blown user registration system. I mean, I’m usually the only user!. So until now, I’ve secured my apps through URL obscurity and no crawl meta tags.
But I recently found a very effective, (and very underrated), Flask extension called Flask-BasicAuth that lets you password protect your apps in 5 lines of code.
Seriously! All you have to do is
pip install Flask-BasicAuth, import it into your app, set a login and password (use env variables!), instantiate it, and then add a decorator to each protected route. Or, you can configure it to cover your entire app.
Don’t believe me? Just read the docs and you’ll come around.
