Changed password, Account 2 appeared

I have changed my password, followed the process and all good. My assets are all there.
However, now Account 2 (with no assets) has appeared out of nowhere! I never created another account, and this account only appeared after the password change!

Has anyone faced this before?

by the way, just noticed the this Account 2 address has no history on Etherscan

sometimes it show up because you accidentally click create account in your MetaMask.
