But just because of a few cybercrime issues, it does not mean that the same will happen to every other user. You just have to be a little more cautious about the safety of your account. It would be good if you keep your Cash app login details a secret because if anyone gets to know your login credentials and access your mobile phone, then the intruder can transfer all the money to their account. Hence, there is a risk of connecting your bank account with the Cash App, but if you are sure that you can keep the funds protected then there is nothing to worry about.
