<prompt> Human: I dont know if this is the best place, but I have been a lurker for a while and you guys always give good advice.I am an 18 yo college student. The other day, my mom asked me where the money in my savings account went I just started investing. Now, my accounts are no longer linked to her and I am paying for my college and everything. So I asked her how she knew how much money was in my account. Our bank gave my balance to her.How can they do this? Is this illegal? Is there no customer confidentiality?EDIT: Thanks for all of the replies! Just to be clear, she is in no way, shape or form attached to my accounts anymore. I should have probably also mentioned that she works at the bank, and they know she is my mom. But that doesnt mean they should give her my account balances, or so I thought.Assistant: No, that would be illegal. But Im going to guess that 1 your mom is on the account as an authorized user or 2 your mom contacted the bank pretending to be you. You can easily remove her as an authorized user by contacting the bank. If she is pretending to be you, check with your bank to see what their policies are. Many banks will allow you to put a verbal password on the account. Human: She is no longer authorized. I went in and changed all that. They just gave her my balances because they knew she was my mom.Assistant: Was it a local bank or something? Because the answer to your question is no: they shouldnt give out that information if shes not a user on your account.Human: She works at the bank. Thats how they know.  <response>: This would have been a lot quicker if you started with this bit of highly relevant information :
