Google Play Games 將會有有改動。過往每次玩一款新遊戲，遊戲若使用了 Google Play Games 服務的，就要回答是否使用 Google 帳戶登入。
在新改動下，玩家只需為帳戶登入一次，而不用再為每一個戲登入。首次登入之後，往後玩其他遊戲時，帳戶就會自動登入。另外，用家亦不用再為 Google+ 帳戶升級，也可以使用 Google Play Games 服務。
– Players are prompted to sign-in once per account, rather than once per game
– Players no longer need their account upgraded to Google+ to use Play Games services
– Once players have signed-in for the first time, they will no longer need to sign in to any future games; they will be automatically signed in
用家若不想使用自動登入，可以在 Play Games App 內的設定將 “Auto Sign-in” 停用就可以。
