Cash app is very sensitive in use, so there are fewer chances of account hacked. You can say that it can’t be hacked until you share your information with anyone. If you get any call who asked you to provide SSN, date of birth, OTP, or any other detail, so you must ignore it to avoid any hacking. If still any issues, please talk to a Cash app representative.
