One of the things I was not expecting when I moved to Amsterdam was its active and vibrant tech community. Appsterdam, a non-profit organization focused around aggregating people with a passion for technology, is probably one of the central forces in this movement.
In my year in Amsterdam I had been to a few meetups organized by people from Appsterdam and always came back home having learned something new. This is why when my colleague Matt (who himself is quite an active Appsterdam member) talked me into presenting a guru session on Google App Engine, I saw that as an opportunity to return the favor.
Google App Engine for Python ships with the capability to manage user accounts without the need of any additional library. This functionality is, however, insufficiently documented. This post is a step-by-step tutorial addressing user registration, login, password reset and a few other details.
