As a user and an educator, I can see that this could provide easy access and flow for teachers needing to use more than one account. Having to remember and keep track of account information is something that I struggle with. People have always mentioned the negatives that can come with having the same password for everything. Well, I think that the same negatives could apply for having a single sign on approach when logging in to an account. The idea that it may in fact, at some point, be misused is enough to keep people from wanting to use this method. If this information landed into the wrong hands, there is far too much available for them to access.
