I cannot emphasize this enough, if you've ever used Twitter credentials to log into anything else you need to figure out how to get out from under that as soon as you can.
@Myphatself@ngsmcphrsn@mhoye I do something similar, and apart from anything else it's enabled me to see at a glance which companies have let my details get into the hands of phishing artists (looking at you, Adobe, as one prominent example) and trivial to then block all email to that address.
