mom put to wrong email and password on i cloud i want to back it up what should i do

Greetings lupe15,

It is not quite clear what has gone wrong with making a backup of your iPhone, but let's see what we can do to get you back on the road.

If you are unable to back up your iPhone to iCloud for any reason, you also have the alternative of of using iTunes on your computer to back up the iPhone. See this article for how to do this -

About backups in iCloud and iTunes - Apple Support

You may also want to change the iCloud account in use on the phone so that further iCloud backups are possible. See this article -

Sign in with a different Apple ID on your iPhone, iPad, or iPod touch - Apple Support

Thanks for using Apple Support Communities.

Be well,

Brett L

Ask mom to log out with the wrong email.
