Create a random token in Javascript based on user details

Question

I want to create a random string (token) which can be used to identify a user whilst avoiding any potential conflicts with any other users\' tokens.

What I was thinking

Answer 1

This function allows you to set the token length and allowed characters.

function generate_token(length){
    //edit the token allowed characters
    var a = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890".split("");
    var b = [];  
    for (var i=0; i

Simply call generate_token

generate_token(32); //returns "qweQj4giRJSdMNzB8g1XIa6t3YtRIHPH"
