Testimonials

It was a pleasure using your extremely quick and efficient random number generator service.

I'm currently using it to assign authentication codes to the users of my PBX system, so I know who's authorized to make international calls, etc. I was facing the problem that if I started assigning authentication codes in serial order, people might guess others' authentication codes and misuse them.

I wish to thank you for putting up this free service for the use of one-shot users like me, I really appreciate it.

Hello! I am an admirer of the Random.org web site! I have implemented a Virtual Coin Toss web page that allows multiple parties in different locations to perform a virtual coin toss which they all can verify separately. On this site, a virtual coin toss (ie, a zero or one) is fetched from random.org once every minute, is stored for some number of days, and can be looked up through a simple form. So, for instance, two individuals can agree to use the toss that will occur at some particular, approaching time; they can then separately view the coin toss as it occurs or look it up later.
