It's common for your previous manager to have temporary access to your machine, files, email and accounts at big companies to support continuity for a few weeks. It'd be in extremely poor taste to post or email as the person but I don't think there's a legal issue per se. It is the companies infrastructure so your work accounts aren't really yours. It's a solid reminder though never to use your work machine for personal use and never to use your personal accounts for work use.
