I get locked out of my kids’ accounts all the time because of password changes. Once my daughter said she didn’t want me to have access and I said “that’s fine” which shocked her. Withing a short time she needed me to do something (pay something? check on something?) and oops, she forgot she’d changed the password (she’s required to every 3-4 months). Even though she is financing her own education too (scholarships, FA, loans), she still needs me (she really needs me!) to handle a lot of the things on her FA account, to pull the charges and payments for taxes, to contact the crabby people at the school when something is wrong. They set up two files for her (error) and because half her documents were in the wrong file, her merit aid was wrong (should have been higher with retake of ACT but the scores weren’t in the right file) and they put a hold on her registration for second semester because they kept saying they didn’t have her hs transcripts. She went to the registrar’s office and they once again told her they didn’t have them and still wouldn’t let her register. I made one call, ended up talking to someone in the FA office, and it was fixed in 5 minutes (they had 3 copies of the hs transcripts, all in the ‘wrong’ file). She was by then shut out of a lab she needed and the only other option was during her practice time. She was very concerned that her coach would be angry. I said to sign up for the open lab time and see if she could get into the other section. Within an hour, her coach had changed her lab time. It is a sad and unfair, but adults have power.
I know you want to be independent, but are your grades really a big secret? Your parents knowing them doesn’t change anything. I give my kids a chance to share them but after a while I do look if I happen to be on the portals doing other things. One of my kids didn’t have great grades in her major, didn’t tell me, and when I finally looked I asked her if she even liked the major. She was so relieved to know she could change her major! She was suffering because she didn’t want to share. She also couldn’t get access to her school account because of bad internet connections when she was taking a semester off and trying to register for this semester’s courses. She told me what she wanted and I did her registration. Parents aren’t always just being nosy. Sometimes we can help.
I’m still on my kids’ bank accounts because I’ve always been, since they were babies. It is convenient because I can make payments or transfers from their accounts. It works for us but if you don’t feel comfortable, don’t give them access (I wouldn’t have given my own parents access) or just open another account at a bank near your school and never put them on it. I do not recommend a general POA. A medical POA can be helpful if you only want one of your parents to be the decision maker.
Are you taking a car to school? Are you independent for that car too? Insurance, registration, repairs?
You need your parents for some things (FAFSA, encouragement, support) and don’t want to cause a war over little things. Tell them you want some independence but still need them, that you want to try to handle your finances and school registrations, etc., on your own but you will let them know your grades and that you will contact them at any time you feel you are in over your head and need their guidance. And then throw them some bones. Which bank should I use at college, Mom? (do anything you want when you get there) Dad, can you recommend an insurance company? Mom, can you go over my vaccination record with me so I understand it?
