It’s pretty easy to remove a second Google account from an Android phone. Just follow the steps below:
Tap the Settings icon (it looks like a “gear” or “cog”).
Scroll down and tap Accounts & sync. You should now see two accounts listed.
Tap the account you want to remove (in this case, your daughter’s account).
Tap the Menu icon (it looks like three vertical dots).
Tap Remove account and follow the prompts as they appear.
