Same issue here too, exactly like you describe. However, I am quite positively sure I have NOT give ANYONE ANY of my keys, not even an entity like 3Speak. So I followed the link that happens to be upvoted by several followers (thank you), and it turns out, my video is apparently gone. :-( So next I try to access my 3Speak - which granted, I don't do very often, and instead of giving me the options of Keychain, Hivesigner, etc. it wanted an e-mail & password. Not knowing which password it could be, I opted to be sent an e-mail which never came. That's when I gave up, as it seemed all too weird for me.
How exceptionally weird... I do use 3speak and log in with email and password, but haven't been in for a couple of weeks.. I'll check it out today and maybe update here. Thanks for letting me know.
