I understand that giving the keys can partially solve the access problem. But she would still possibly be unable to use the device. Additionally, I don’t know that she would be capable of using the keys without additional assistance and we don’t have other techies in our community who could step up in that capacity.
It is the largest reason. Storing the password is one thing but to make the device reasonable to use I would likely store the key’s in TPM with a backup key. I don’t think she would be technical enough to use the backup keys were something additional to happen.
