This user details is not stored in my chrome auto fill. I didn't know this user.

Issues like this get reported every month or so. In every case we've ever seen, this problem happens when a user either loaned their device to someone else temporarily, or, more commonly, they themselves logged in from a shared device (either a kiosk computer, borrowed a friends, etc) with sync enabled for their Google account.

If you provide info on the Google account you use for Chrome sync, the sync team may be able to look into Logs to see where the problem arose.

+Gang, current on-call client bug fixer for Sync

raj.nishant360@: could you please provide a screenshot of chrome://sync-internals from your Android phone? Also, do we have your permission to look at our server-side logs for your Google Account to see where and when this saved credential got synced to your account?
