Random Number Generator

Adding numbers to your passwords makes them more secure. In fact, most sites and services these days require alphanumeric passwords at the very least. Some people have also started including numbers in their usernames and email addresses to keep their accounts unique. And of course, even with multi-factor authentication (fingerprint or face scan), most devices these days still require a numeric passcode.

You might already have a go-to number — your pet’s birthday, your wedding anniversary, the address of the house you grew up in — but as best practice, we recommend using a random number instead.

We built this free tool for exactly that. Customize it to your needs, and use our random number generator to add numerals to your passwords and account usernames, create hard-to-guess passcodes for your phone, or even set your bank card’s PIN.

How Our Random Number Generator Works

Our random number generator uses a computer algorithm to select a random number within a set range, using randomized mathematical functions for the selection process. It’s also called a pseudo-random number generator (PRNG), because the algorithm may have selection bias.

Still, for most applications including the examples we mentioned above, random number generators like this one provide adequate randomness.
