Internet is not horizontal, it's vertical.
Guys,before we go all crazy I think you deserve an explanation on how the SSO works and why we haven't implemented the feature you request (yet). This doesn't mean we are looking into feasible methods, but for now it is not possible because:- the SSO (single sign on) system resides in its own separate server protected with a certificate to ensure there is a secure connection and that your usernames and passwords don't fly over the internet unprotected- the different websites are having their own way to identify users and we make them request a secret token from the SSO server to identify the user and make sure he/she is logged in- the scenarios you guys suggest imply that, at this point, we should let the passwords fly freely from e.g. the forum into the SSO server and that is a solution we are not willing to implement because of its high riskIn other words, we understand he usability issues mentioned in this topic, but it is nothing we are going to implement now since it would mean putting the whole Arduino website under https, which according to some reports it could slow the server up to 5 times depending on the case. We need to make a lot of performance tests before we can do that.
