37Signals rolled out 37Signals ID – a unified, single sign on system for all their products recently. The feature invited a lot of heated arguments, but promises interest integration opportunities.

Transition to the new system was very smooth. A page asking you to select a new username, easy automated checking of usernames and useful suggestions about available usernames, and a one click, quick submission. The email notification too is well designed just like all other 37Signals products.

I was expecting we will have to do some changes on PlannerX for the new system to work. I was gladly surprised that we did not! You can continue using PlannerX with the new Basecamp username / password (the old ones won’t work, obviously). You don’t have to make any change to PlannerX!

Smooth!
