Since I upgraded to Lolipop 5.0, why do I have my co-workers personal data cached in my phone?

[AC Question]

Upgrade to Lolipop 5.0 - Now have co-workers personal data cached in my phone

Long story short - Upgraded today on work WIFI - went to amazon.com via Chrome on my S5 - his login data was there. Logged in, his CC information, address, etc. all accessible.

He does not have access to my phone as I'm on a secure floor at work and my phone never leaves my pocket. Never...

How could this happen?

Welcome to Android Central! Is it possible you were logged into Chrome on a desktop browser somewhere in the office, forgot to log off, and your coworker started using that same browser, not realizing it was logged into your Google account?

On any desktop browser, go to a Google page, then click on your profile picture at the upper right, and then click Account. Scroll down to Devices and Activity, and see if there are any sessions that shouldn't be there.
