To log out of your Monopoly Go account, start by opening the game. Tap the three bars icon at the top right of your screen. From the side menu, choose Settings. Next, tap Connect Account. Here, select Disconnect on either the Facebook blue button or the Apple/Google green button. Confirm your choice by tapping Disconnect again in the pop-up window. Finally, close the game to complete the process.
If you want to switch to another account, open Facebook in your device’s web browser. Log out of your current Facebook account and log into the new account you wish to link to Monopoly Go. Then, launch Monopoly Go again. Tap Play With Friends and follow the instructions to link the new account.
Be aware that logging out without linking to another account will result in playing on a guest account. This may lead to data loss if you delete the app data. To prevent losing your progress, sign into another account immediately after logging out.
