@haarchri I pushed again now. I changed the example region to us-east-1 and added a VPC to get a complete example. The existing region has only two az-s per account so it's not good for examples.

I'm a bit confused as I don't remember getting an error about needing a VPC to use auth tokens the last time I tested, but now I do. This is why I added a VPC to the example.

@turkenf @ulucinar Thanks for the review! I think the two remaining comments apply to common.PasswordGenerator in general?
