It’s been the same person for almost 5 years. Trust was built over time.
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.
