Creating a User Login System Using Python, Flask and MongoDB

You'll learn how to create a login system using Python, Flask, and Flask-PyMongo in this video. It's a common need for any web app, so watch this video if you haven't built your login system yet.

I can't thank you enough. Without this video, I would spend days or weeks trying to learn the same thing from other online resources. You have this incredible ability to make this a lot easier. Thank you so much!

I have to give you mad props for one thing: You do give a decent walkthrough of your stuff.

A lot of other "instructors" would not allow themselves to make an error or a typo, and effectively would re-do their casting to show themselves as perfect coders, often times confusing people as to "wait... why did he do this and not that?"
- "WELL if u had seen the bloopers, u'd have known that the other way nuked the world!"

But you post it with the very trivial mistakes that many coders do on a daily basis because we're all human, and that's inspiring for new-comers in python/Flask like myself :)

Great video, my first attempt at python and got this working. Would be great to see a follow on video extending this with a todo. Thanks.

thanks for the awesome tutorial, it helps me a lot !

I use python 3.5.2, when I execute, there is an error message in line 25:
AttributeError: 'bytes' object has no attribute 'encode'

After some try, the problem is, and I delete the encode part. Just use 'login_user['password']', then it works.

Just want to share with someone stuck here like me.

Hi there please can you make a video on how to use flask-login with flask-PyMongo, i am having trouble setting it up. All kind of references are also accepted.Thanks.

Excellent!, just a heads up, the user doesn't know if the username or password is wrong, but if they think a little more, they will find out that the username exist because of the delay while trying to hash/compare the passwords :) so all that is left is try to bruteforce :D

Great video. Really helped me create a user login with mongodb with ease. Thank you. Can you please also add a video for user logoff with flask/mongodb?

Hey Anthony,
I got the following error while following your tutor;
sock_info = self.sockets.popleft()Open an interactive python shell in this frame

[hasnenkhan]

what if user enters the url of the page directly...how to restrict that

[MatthewWhiteMW]

I'm getting the following error 'TypeError: 'Collection' object is not callable. If you meant to call the 'encode' method on a 'Collection' object it is failing because no such method exists.'

python 2.7

[radhikamanivannan]

awesome tutorial for a beginner like me. Thanks alot. Found it very helpful!!..:D

[ananay]

My return redirect(url_for('index)) doesn't work in the register. It doesn't redirect to the page at all. Does this have to do with being POST instead of GET? Can someone help me as to how to redirect to the desired page?
