Apple ID
I went through the process to update my Apple ID password for a different Apple ID then is listed on my phone. This process took over 2 weeks! My phone has an iCloud email. How do I now get a new password for my iCloud Apple ID?
If you know the Curren password.
What to do after you change your Apple ID or password - Apple Support I suggest doing this before you change your Apple ID or password.
