No. Once a Dragon City account has been linked to a Facebook account, Google Play Games account, or Apple ID, that connection is permanent.

For this reason:

• The linked Facebook, Google Play Games, or Apple account cannot be changed.
• Game progress cannot be transferred to a different Facebook, Google Play Games, or Apple account.
• A linked Facebook, Google Play Games, or Apple account cannot be unlinked from the game account.
• Progress cannot be merged between multiple game accounts.

If you want to continue playing with your existing progress, you must log in using the same Facebook account, Google Play Games account, or Apple ID that was originally linked to the game.

To avoid losing access to your progress, make sure you keep access to the account linked to your Dragon City game.
