Cash App , by Square , is a convenient peer-to-peer money transfer app that allows you to exchange money with friends and family on your phone, without any actual money actually changing hands. Gone are the days of counting bills and divvying up change at restaurants if you and your friends have the Cash App then you're all set.

Of course, if you have an app that sends money to other people on your phone, it's reasonable to want to keep it extra protected. That's why the Cash App offers the option to either scan your fingerprint or enter a PIN before you send money to others. This setting can be turned on in the "Privacy and Security" section of your account.

However, it goes without saying that if you opt to use a PIN, there's a chance that you'll have to change it someday if it ever becomes compromised or you forget it. Luckily, the Cash App makes it very easy to change your PIN using your iPhone or Android .
