python - Flask user authentication -

i have application use flask , mongodb; host on rackspace.

i need understand how flask authenticating works. have not found information on subject. there complete tutorial on how roll own solution? if not, hear thoughts on how approach a flask app.

big ps:

i thought it. need open real api. part of api used ajax on front end. how secure part of app?

i suggest using flask-login extension, makes session management easy add flask application, , provides nice documentation covers in details every aspect of extension.
