Like, I want to make my password really strong

But why then am I limited to a max of 20 characters?
My desired password is at least twice the size of the max limit.
Come on ROBLOX, let us protect our stuff more.


According to
A twenty character password with all lowercase would take 157 Billion years to hack with a desktop pc

A twenty character with random symbols and other stuff that I just generated will take 3 sextillion years with a desktop pc
Thats 3,000,000,000,000,000,000,000!

Now, also keep in mind that even if you had a computer 157 Billion times faster than a desktop, it would still take a year to hack

Just also keep your password from being guessable

--Generate a random 20-digit password
local pass=''
local g = {}
for _, v in next, {{48, 57}, {65, 90}, {97, 122}} do
	for i = v[1], v[2] do
		g[#g + 1] = string.char(i)
for _ = 1, 20 do
	pass = pass .. g[math.random(1, #g)]

Using that as a password generator is extremely terrible. Pseudo-random number generators do not have enough entropy to be used for password generation, so they will be extremely easy to break based on the sequence produced.

It’s not like true random would be any better. It would allow the chance for a password to be “aaaaaaaaaaaaaaaaaaaa” (or any other combination of characters)

I know, I was disappointed I couldn’t put my roblox password to something like

We are working on a feature to allow longer passwords. Soon ™

Edit: And 2 Step Verification also coming Soon ™


No, you’re confusing passwords with encryption keys.
Rule of thumb: The easier it is to memorize, the easier it is to crack. Most password crackers use dictionary attacks or similar heuristics to weed out passwords that are easy to memorize.

I plugged a few generated passwords into


Actual protip: Don’t disclose any information about your password, as that can be used to crack it.

e.g. Don’t brag about how awesome and smart you are for using the xkcd method to generate your passwords. You are not smart. You are very dumb.


I mean, if you want to crack a 64 character password… by all means.

Yea, I run some of my sample passwords through Rather useful.

If each password is encrypted into a 20-character string, passwords longer than 20 characters are literally not more secure because they would be equivalent to some shorter password (probably multiple.) Someone/you could put in some other password and get into your account it they encrypt the same.

It would be better to just roll a dice on what to choose. even number roll, choose a letter. odd roll go for a number. Then do a roll again for the letter if its capitalized or not. And then continue that for each character. It’s overkill imo though

Nice im gonna make my future passwords 111111111111111111111 because that will take 7 billion years to crack. Or the random kid who has nothing better to do than to guess passwords on accounts and accidentally gets it right

Through a 0 in there, it’ll never be cracked!

Hm. A binary password seems like fun! I’m totally going to do this!

Not really that secure, as it would be pretty easy to run just a numbers through the crack. Keep in mind, this is with a “desktop PC”. I do know of a computer setup that can run ~100 times faster, running off of 25 GPUs. This brings that number down to 70 years. Do you only want a 70 year password that could be even easier to hack guessing patterns?

I pasted a password from a password generator into over and over until I got this:

One more digit and it hits infinity.

Just for the heck of it, I put the url to the above image in. It would take a desktop PC about a tredecillion years to crack it.

My full name would take about 24 thousand years to crack.

This is fun.

For those who wanna know how big that is: 24,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
or 24*10^288
