How do I set my gmail account as permanent default on my Galaxy phone?

[AC Question]

On my phone, Galaxy S5, I have 2 gmail accounts, mine and my daughter. Whenever I try to download an app, login to a site or make a purchase, her account takes preference and I can't get back to mine. I went into settings and thought I changed it, but anything I try to do continues to revert back to her account. How do I set MINE as permanent default?

The first account that you login with will be the default. So remove your daughter's account then add it back again.
