Is it always the same person? How do you build up the trust to let them mess with your bills/tickets/money?
She doesn’t have direct access to my money, only credit cards. Those are easy to cancel or chargeback if things go screwy. She does know my SSN which is a bigger concern, but then again you give your SSN to all sorts of people and services in USA, it’s very not actually a secret.
Oh and she doesn’t know passwords to anything. LastPass sharing only.
