Brute force protection
It’s not quite complete without code on the password reset page to tell you that you can’t reuse your password.
And label the text box “username” when it only accepts email address.
Don’t forget to have hidden password requirements and secretly truncate any password longer than 12 characters.
Well yeah, if you don’t truncate the password to 12 chars how will you fit the plaintext in a memory efficient fixed latin1 CHAR column that only accepts letters, numbers, and underscores
/s
Battle.net used to not be case-sensitive for passwords, back in like the pre-wow era.
And then validate the email with a custom regex that definitely doesn’t account for all the valid syntax permutations defined by the several email-oriented RFCs
Only on mobile though, on desktop have different criteria. Perhaps give the text box an arbitrary max length of like 30 characters on sign-in but not on account creation.
I swear this is what some websites do
Cell phone lock screens too.
Also USB cords
This could actually work though lol, it’s genius
Rainbow tables and presumably newer stuff I haven’t heard of make this sort of thing weaker than it used to be
How does a rainbow table help here? They’re more for decoding unsalted encrypted database tables, rather than for actually trying to login.
Salting makes rainbow tables pretty much useless, and salting has been a standard practise for a few decades now.
Dictionary attacks have been around for a long time, but It’s still quite strong especially if you throw in a number.
A fully random 8 character password has about 10^14 brute force combinations (assuming upper and lower case + the normal special characters). 4 words choosen at random from the top 3000 words (which is a very small vocabulary really) is 10^13 dictionary attack combinations, add a single number or account for variations in word style (I.e maybe don’t always use camel case) and you’ve matched the difficulty. If you use 5 words it’s 10^17 combinations.
A password manager and a hard password is a better idea but there are cases where you can’t use a password manager (like the password to said manager).
I’m a basic little shit so, I basically use a correct horse + number password for my PW manager
I use a whole sentence with a typo lol
Something like "On March the 3rd of 2012 my dog Billy ate 8€ worrth of schmeggles!“
Yeah I thought about adding a note that it’s pretty outdated - and dictionary based scans were always possible even if less common in the old days - like those infamous passwords “God”, “Love”, “secret”, or like “admin”.
The artist is pretty smart most of the time though so I presume they were aware of that possibility and meant that on a more basic level there are multiple ways to make passwords easier for a user to remember, not necessarily just this one rather simplistic take but as part of a whole approach. Then again, they didn’t say that, and instead said this, thus the controversy.
Personally I gave up entirely and now I don’t even know what any of my own passwords are, though my password manager does:-). I guess… if you cannot beat them, join them!?:-P
My current favorite “memorizable” method (obviously a random hash from a PW manager is still better) is to take a sentence of moderate complexity that includes the name of the service you’re signing up for in it, and use the first letter of each word as your password.
For example, “When I wake up in the morning, the first thing I do is go to pawb.social.”
Password would be “WIwuitm,tftIdigtps.”
Easy to remember, immune to dictionary attacks, and you get a (mostly) unique password for each service, so stolen passwords can only access that one thing.
Edit: To be clear, the value is that you can use the same sentence everywhere, switching out the name of the service to generate semi-unique passwords for each service. Obviously someone analyzing your passwords would be able to figure out the pattern, but that’s basically never what actually happens; it’s more likely someone gets 1 password and tries your email address + that PW in a variety of services, which this is strong against.
This seems like a memory method for someone who has a great memory. (Better than mine anyway)
It’s surprisingly easy to memorize. The sentence basically acts as a mnemonic device to remember the password, and it’s a lot easier to memorize a sentence that makes sense to you than to memorize something like “Tr0ub4d0r&8”.
The rainbow table would have to include every four word combination. At around half a million words in the English dictionary, that’s not a small number.
As another XKCD comic illustrates, it’s cheaper to use a wrench.
Example of what My passwords are like :
%*7EfOLkN!8Dl#
or potentially if allowed :
W@c2wYnN9J3xGcyc47#ZkHJvt&Hm%q&Ad0b&Xwz#jnl4Th%6UBexD16a$YBFc@svnVrCBxXP0EpwLp6%Gk*Lom%@Qq#DjY1zsf0CzIrHHqPc8gt4edDVsg!omj*kIsIJ
Good luck guessing my shit.Amateur! Strong enough passwords are like:

You lever is very low! There are not displayable characters so you cannot easly verity the password by eye or copy from paper.
Why would I have to verify by eye? That’s what a password manager is for. And writing your passwords on paper? ಠ益ಠ
Sometimes you have to give a password to a friend on a paper or by a phone.

Entropy so strong it makes quantum computers cry.
You fool, you utter buffoon -
This is what a strong enough password looks like
I suspect if the cracking code was constructed such that it had more weight on trying combinations of common words then this would be much easier to crack
I would naively think that as well - you would expand your alphabet of “symbols” to include both single letters and numbers and punctuation but also common words as well. It is still a lot of combinations to have to try though, even if less than each letter by itself.
As a non programmer, is the joke that humans will retype their password assuming that they made a typo?
If so, sick indeed.
The guy coding made it so, on your first attempt, even if you answer correctly, it will tell you your login failed due to incorrect username or password, to joke about how it feels like you always get it wrong on the first try
The logic is bugging me, though. It should be
if isFirstAttempt || !isPasswordCorrect
I understand the meme is trying to convey in spite of being correct to still return an error, but then it doesn’t account for when the password is actually incorrect.
That defeats the brute-force attack protection…
The idea is that brute-force attackers will only check each password once, while real users will likely assume they mistyped and retype the same password.
The code isn’t complete, and has nothing to do with actually incorrect passwords.
Like the other person said, it’s not meant to always fail the first time you enter any password.
It is meant to fail the first time you enter the correct password.
Yeah, hackers have automated tools and they will, of course, only try each password once.
@gibmiser
Yes exactly 😂
Fine I’ll just change my password to what I thought it should be.
*New password cannot match old password
took me a solid 30 seconds of re-reading to get the joke
The one guy got grey hairs in-between slides lol
I remember in college editing OpenSSH source code to instead of return wrong password to a root shell prompt just to stop brute force attacks
But… arent they logged in as root then? Wdym with “prompt” i am lost
@Pacmanlives
Couldn’t you just disable root login in the sshd config?Oh all of my configs are deny root ssh login or without-password. I noticed a significant decrease in scans when returning a root prompt when I did that. This was also in the mid 2000s so who knows how things would be in this day in age for a reduction in scans
@Pacmanlives
So it was a fake root prompt which tricked the bots into believing that they logged in successfully but in reality the prompt could do nothing on the system?Correct
Well, I sometimes input the same password 15-times in a row, and it works only on the last try. ¯\_(ツ)_/¯
if isFirst14Attempts
That’s actually pretty smart
Add a randomizer with 50/50 succeeding for this error
If they had the password right the first try, that isn’t a brute force attack, thats a credential leak.
It should be that it rejects the password the first time it’s entered correctly but accepts it on every subsequent try. That actually would provide some protection against like dictionary attacks and raw brute force attacks.
I think the author attempted first time login to be with the right password.
Best idea ever!!!
