A simple Flask extension implementing Olin's authentication

Project description

Flask-OlinAuth implements OlinApps auth. It automatically provides a /olinauthlogin and /olinauthlogout route to the application, handling the process of actually authenticating a user with olinapps.

At a high level, Flask-OlinAuth provides two useful pieces for your application, both of which are demonstrated in


A simple function decorator which ensures that a user is logged in before a view is shown. The user is redirected to the login portal, with correct arguments, if not.


A nice local proxy for all of your views to get the current user, formatted as a dictionary.


Will log out the currently authenticated user, allowing you to simply create your own logout view.

Flask-OlinAuth is very heavily inspired by Flask-Login, with structure, and functionality adopted, and much knowledge gained.


Install the extension with one of the following commands:

$ easy_install flask-olinauth

or alternatively if you have pip installed (which you should):

$ pip install flask-olinauth

Example Usage

from flask import Flask, url_for
from flask.ext.olinauth import OlinAuth, auth_required, current_user
app = Flask(__name__)

SECRET_KEY = "yeah, not actually a secret"
DEBUG = True


oa = OlinAuth(app, 'localhost:5000')
#initial OlinAuth, with callback host of localhost:5000, for local server
oa.init_app(app, 'localhost:5000')

def index():
    if current_user:
        responseString = "Awesome index, guess what? %s is logged in. Sweet, right?" % current_user['id']
        responseString = "<html>It is kind of lonely here... No users are logged in. <a href=%s>Checkout my secret</a> </html>" % url_for('secret')
    return responseString

def secret():
    return "I wouldn't normally show you this, but since %s is logged in, here is the secret: 42" % current_user['id']

if __name__ == "__main__":
