The longer pattern the better.
Let’s take 8 characters long strings for example:charset = 0123456789 abcdefghijkl mnopqrstuvwxyz ABCDEFGHIJKLM NOPQRSTUVWXYZ — 63 characters. In this case there are 63⁸ = 248155780267521 possible codes. It means that if you issue a billion codes the probability of guessing a code is 10⁹/63⁸ = 0.000004… — 4 in a million.
Generated codes can be used as promo codes, voucher numbers, gift cards numbers, referral codes, serial numbers, lottery numbers, strong passwords, and more.
