My mother-in-law's cognitive abilities have declined and she has given me a power of attorney to handle her affairs including paying her bills. I need to look at her email periodically to see if there are any bills that need paying. I have the password to her account but can no longer log in -- a visiting grandchild might have changed it (happens occasionally) or Apple has done something (I am in a different country). My Google Voice number is the second number associated with her account and in the past this has enabled me to reset her password. Now that no longer seems to work. I tried to use iforgot.apple.com, but that requires knowing the pin/pw for one of her other devices. I don't know that (may have changed also). I would like to figure out a) how to reset her password remotely; and b) change her account so it is linked with my Google Voice number so that I can have continuing access to her emails. She is using her iphone for calls and Facetime. Can you help me with both of these issues?
I have an iphone and a number of Apple devices. In making this change I don't want to delink my devices from my appleid.
