how do you signout of your sims4 account to login into a different account

@IAmHellDog  Quit Sims 4 and the EA App should pop up.  Click the three bars in the upper-left corner of the screen and select Sign Out.  You'll see the login screen for the App and can then sign into a different account.

@8vveq7ctctkv  In the Windows version of the EA App, the three bars are in the upper-left corner of the App window.  In the Mac version, you'd select Account in the menu bar along the top of your screen.
