The 5 digit pin is an electronic filing pin that you create for your signature. Each year you can create a new pin, you don't have to remember the one that you used last year. If you've already entered it, you don't need to change it.
For more information, review What's my signature ID? and the IRS article Self-select PIN method for Forms 1040.
