Alphanumeric symbols are characters that include both letters (alphabets) and numbers (digits). Specifically, they consist of the 26 letters of the English alphabet (both uppercase and lowercase) along with the digits 0 through 9.

Decide what symbols you want to allow. For example: 26 uppercase letters + 26 lowercase letters + 10 digits = 62. Or less, if you don't want to distinguish uppercase and lowercase; or more, if you want to allow certain special symbols such as spaces, hyphens, etc. Raise this number to the sixth power, if you use 6 characters.
Alphanumeric characters means any combination of letters and digits. Sometimes other special symbols are allowed, too - so alphanumeric may sometimes be understood to mean a combination of just about any type of symbols.
