save license key and that you are logged in

im developing a programm right now using javascript and a pocketbase. im right now working on license keys. if you redeem a licnse key it will set a variable in the data base to true (the redeemed variable). how can i now make it so when u start my programm it wont ask for a license key? (like that u save it somewhere that u put in the license key already) *im using license keys so u need to have a wifi connection one time and after that you wont need to have one so u can work offline*
