You might benefit from compartmentalizing your sensitive information. Realtors often use custom-purpose sticky notes to help people navigate paperwork, like a little yellow arrow that says u201csign hereu201d or a blue flag that says u201creview these options.u201d Perhaps your assistant could fill out the entire form for you, except where your SSN needs to be provided, and call those lines out to you with a little sticky arrow.When calling the bank, you may have to initiate the call and then allow your assistant to take over. That way, youu2019d prthe sensitive data to the bank and satisfy their identity verification, then youu2019d authorize your assistant to speak on your behalf about the account, and let them take it from there.If you have any tasks that require sensitive data to actually conduct the business - say, moving funds between several bank accounts, which would require constant access to account numbers and other info - then youu2019ll have to give that task to someone you trust with that info. If youu2019re the only one you trust, youu2019re the only one who can do the task.
