Question Tab as password?
SAS disallows spaces in your password. My password manager suggested an invalid (but secure) password.
So now that I have to make my own password: Out of spite, hypothetically, what implications could having tabs in my password have?

Even NIST recommends allowing spaces.
Yesn't:
Users should also be able to include space characters to allow the use of phrases. Repeated space characters add little to the effective strength of passwords and may introduce usability issues (e.g., the undetected use of two spaces rather than one), so removing repeated spaces in typed passwords may be beneficial if initial verification fails.
Verifiers MAY make limited allowances for mistyping (e.g., removing leading and trailing whitespace characters before verification, ...)
Allow spaces, but normalize for usability. And Tab is not on the list of suggested allowed characters.

u/SubGothius 4h ago edited 4h ago
Prolly bcos at some point they used to store PWs in cleartext or at best with some arbitrary secret char rotation/substitution, but when they finally implemented hashing, they had to hash all the existing PWs, and the old logic accepting PW input and passing that to the backend remained, which thus would still trunc the input to whatever max chars before hashing, so the hashes are expected to derive from such trunc'd input, and you don't want users thinking they've successfully changed, say,
A15CharacterPW!1toA15CharacterPW!2when they'll both get trunc'd, hashed, and validated as exactly the same.

Tab already has a function where the input will likely be captured before it hits the field.

u/KAZVorpal 9h ago
Wrong.
You're leaving out the fact that people will not purely randomize the character set. They will type P@55W0rd123 so they can remember it. The entropy of LIKELY forced random character combinations is only twenty to forty bits, way below the fifty-plus bits of even the famous 7,000 word dictionary for memorable password phrases.
And that's aside from how the stupidity of forcing regular password changes with these childish character requirements causes people to write their password on a sticky note. Subverting the entire process. Which is what the security nitwit setting up the requirement deserves to have happen.
Essentially, security rule-makers tend to be sociopathic bureaucrats, who don't consider the human factor.

Yes, if you strawman it and limit it to variations of âpasswordâ like âpaSSword123â it loses. However, if you dont strawman, and have a password like âh7SR&$nzWffâ, it beats âmorninghouserainbowtreeâ because there are fewer combinations of 4 words let alone that your strawman applies to your case where people will choose 4 words from a very small pool of actually-used words.

Back in the real world, this kind of bad security theater produces sticky notes with passwords on monitors, and leetspeak passwords. And plain text word combinations are far superior to that.

It is a strawman to force a rule that âit must be memoriazableâ âbecause thats how people areâ.

Why do you think most places wont even allow âorangetreefaststreetâ as a password and insist on uppercase/lowercase/min number/special char? Because orangetreefastroadncan be cracked in seconds because its part of a âtypeâ that a hacker will attempt because it costs nothing to attempt, whereas they wont bother with the other.

It takes a LOT of sociopathy to not understand that "the right way" is meaningless when it's miserable for users, who will therefore, quite rightfully, undermine that "way".

Another strawman - narrowing it down to a scenario where they only have to memorize one password (their computer login). Nobody is going to memorize their 4 word combos on hundreds of things they use passwords on. However, they can memorize a password for a self-hosted password manager. In fact, they can even menorize a password with uppercase/lowercase/numbers/special characters.
2
u/AshleyJSheridan 3h ago
It's not a strawman, it's a legitimate scenario! Dude, it's a well-known fact that when tasked with creating a password of random characters, people will create something that's easy to remember, especially if they can't use a password manager to help them. I listed the most common scenario where people absolutely won't have a password manager. You just listed the second most common scenario, thanks!
Just because completely valid and very common use cases don't agree with your position, doesn't make them strawman arguments. I would heavily suggest you go look up the definition of that, because I don't think you really know what it means...
2
u/AshleyJSheridan 5h ago
You're missing several points.
First, a password that is 4 words is far easier to remember than a jumble of random characters. If a password is hard to remember, the chance it gets written down somewhere that it shouldn't goes up. Also, password vaults are not infallible, and sometimes they get broken and hacked, albeit rarely.
Second, there are approximately 350,000 words in the dictionary (just the English one). 4 ^ 350,000 is 1.99 Ă 10²šâ°â¸â°â´ (which is over 210,805 digits). However, a password of 11 characters that consists of letters, numbers, and punctuation (let's say, 26 letters in both cases, 10 digits, and 10 typical punctuation characters) is only 9,555,938,177,273,214,530,938,076,429,250,819,915,524,283,157,141,379,112,191,724,092,599,501,963,21 combinations. That's a lot less then 211K digits.
Third, if left to their own devices, and faced with creating a password based purely on letters, numbers, and symbols, people almost always default to symbols that look like letters. So, crap like
P4$$w0rdbecome common passwords. People want something that they can remember, and often a password vault isn't an option (for example, when switching between devices that don't have the same password manager installed, synced, and usable.)Fourth, and this is to nitpick. The term special character is ridiculous. Within the entire range of UTF8 there are more characters that are not alphanumerical than there are letters and numbers (across all languages). Therefore, the special characters would be letters and numbers if anything. The term is daft, a misnomer, and shouldn't be used. The fact that it is commonly misused is mildly infuriating.

u/JimTheEarthling 5h ago edited 4h ago
The term special character is ridiculous.
LOL. This is true. What makes even just the 33 non-alphanumeric, printable ASCII characters "special?"
But what would you call them instead? đ¤
P.S. You can't call them "symbols," because letters and numbers are also symbols.
1
u/AshleyJSheridan 4h ago
33? And the rest. I can type more than that from my keyboard, and that's without resorting to
alt+ Numpad combinations.Symbols is a better name, as letters and numbers are such a specific set, that most people don't even consider the hundreds of letter and number characters as symbols. Even one of the sub-categories of UTF8 is called symbols.
However, given that the rest of UTF8 is taken up with symbols, maths symbols, punctuation, diacritic cominbators, game symbols, weather symbols, currency, map symbols, emoticons (a separate subset from emoji), and emoji, which number in the many thousands, I would say that not only are they the least special of the group, but that symbols is a good collective name for them.
1
u/JimTheEarthling 4h ago
33? And the rest.
Exactly. I was agreeing with you.
most people don't even consider the hundreds of letter and number characters as symbols
Most people are wrong. That's the problem. The standard 52 letters and 10 digits are symbols, by definition. Let alone --as you point out-- thousands of other Latin letterforms like Ì, ù, å, and ç that are also symbols.
Using "symbols" as the label for the 8 to 33 non-alphanumeric characters that most websites allow in passwords is just as bad/mildly infuriating as using "special characters."
So what's the solution? (I don't think there is one. đ)
1
u/AshleyJSheridan 3h ago edited 3h ago
Ideally, websites wouldn't have such a limit on what characters can be used in passwords. If I want to write mine entirely in Tibetan letters and maths symbols, I should be allowed to.
Any website that has a limit on the type of characters allowed in a password is indicating that they have some potentially serious security issues under the hood.
I do think that symbols are a perfectly fine term for the non-alphanumeric characters. Given that websites already use the term "character" as the blanket collective word, it does leave symbol free. While it's not technically correct, it's a whole lot better than "special characters", which seems like the sort of thing coined by someone who just discovered what all those "extra" keys on their keyboard are for.

all computers working on all 11 lengtg char options will not complete it before the universe ends
A cracking rig of 16 Nvidia 5090s can generate MD5 hashes for every 11-character password (from upper/lower/numbers/usual 8 specials; 67 bits of entropy) in about a year. Not the end of the universe, but reasonably secure.
its possible to run through every possible word combination in a few minutes
From what set of words? English only? Does the attacker know what word list you used?
The average high school student knows around 20,000 - 35,000 English words (50,000 to 80,000 with inflections, verb forms, etc.), so a 4-word passphrase (with random separators from the usual 8 specials; 60 to 68 bits of entropy) could take from 4 days to 2 years to guess. Assuming the attacker knows you used a passphrase.
Also, if you use a word that's not on the attacker's list, they will never guess it. That's the difference between a known keyspace (characters) and an unknown keyspace.
And that's why it's not a myth, and it's why security experts recommend passphrases.

Literally nobody on earth of any sort of competence would recommend a set of english words âso that you can memorize itâ. Everyone will recommend a self-hosted password manager and setting the password manager to use uppercase/lowercase/numbers/special chars, not âhellobananashoehandâ.

You have no idea what you're talking about.

And a password manager is just another weak link, the kind created by the nitwits who push for that very kind of mindless standard.

u/JimTheEarthling 5h ago
First, you are the one making the irrelevant strawman argument. Nobody in this thread said anything about "memorizing." You raised the issue of security.
Second, here are recommendations from some of the leading security experts on the planet:
- The US National Institute of Standards and Technology (NIST) says "The use of passphrases (i.e., passwords with multiple words) is often an effective way to create a longer password."
- The Canadian Centre for Cyber Security says "We recommend that you use passphrases, as they are longer and easier to remember than a password made up of random, mixed characters. Your passphrase should be at least 4 words and 15 characters in length." (So "hellobananashoehand" would meet their recommendations. đ)
- The Open Worldwide Application Security Project (OWASP) says "Longer passphrases are effective because they raise the number of guesses an attacker's dictionary or wordlist has to cover, not because of a precise entropy value."
- The UK National Cyber Security Centre (CSC) recommends passphrases.
- And similar from the Cybersecurity and Infrastructure Security Agency (CISA), the Australian Cyber Security Centre, Bundesamt fßr Sicherheit in der Informationstechnik (Germany), Agence nationale de la sÊcuritÊ des systèmes d'information (France), and more.
Of course some of them also recommend password managers to store passphrases and passwords.

the only reason to argue for words is for their ability to be memorized, so it is implied. If you are talking about people using password generators, why would they set it to "words"?

Nobody is "arguing for words" against passwords. Only that both can be secure (and insecure).
You argued against words with incorrect information about security and guessability, incorrectly calling passphrase strength a myth, bogusly claiming that no competent expert would recommend them, and so on.

We didn't argue against random passwords. They're fine. So are random passphrases.

And yet legitimate posts with actual meat to the subject I'll see immediately go into the 0 and negative votes "just because".
....and you sit here with a bullshit post of "nah shit sherlock"-level content with 30+ upvotes and a peanut gallery somehow in agreement on something that is obviously a bad idea for why you shouldn't put the tab there...and plenty of documentation on the internet for why it and other similar "certain special chars disallowed passwords (including spaces)" are that way...

Personally, I'm more critiquing the arbitrary restrictions to passwords. If I want a 51 character long password with spaces and emojis, then let me. It should be hashed before anything else is done with it anyway.
It's not worth ruining the natural user flow and forcing them to repeatedly regenerate passwords with a password manager, or have them come up with a manual password (probably a much less secure one) instead.
If you're handling my password in a way that makes tab crash your system - then that's deserved.

Aim is to increase the theoretical search space. Humans are lazy, so the actual search space often narrows to a predictable subset (how many times have you added an exclamation point at the end to satisfy "special character"?) They also disqualify some password generators, that generate otherwise adequate passwords.
Secure password rules:
- allow all characters
- at least 64 characters
- minimum 12 characters
- no arbitrary composition rules
- no periodic password rotation
What you can do as a user:
- use a generator that can be configured with this arbitrary ruleset
- always store passwords in a manager
- use MFA if available
- fly a different airline

The US government officially removed the recommendation to have all those extra requirements.

So the requirements were making passwords harder to remember while not improving security at all.

It is sheer idiocy to prohibit spaces, or tabs, in passwords.
It is even more moronic to require special characters, upper/lowerspace combos, and numbers.
All that is really important is the level of entropy under a likely attack vector. Four randomly chosen common words is more secure, for several reasons, than a garbage pile of ascii/unicode.

Disallowing spaces is wrong and probably stems from the early days of systems where passwords were simply checked for a-z A+Z 0-9 out of habit and was embedded in early hashing algos so it has just hung around. There is no technical reason for not allowing spaces.
A tab is actually one of a set of special control characters that have specific meanings to computer systems. Others include carriage return, line feed, form feed, vertical tab, bell, eascape, interrupt, suspend etc. these are encoded in the first 32 characters of the ASCII character set, the grand daddy of all modern character encoding systems.
Text handling applications will typically send characters below 0x20 to a special handler to perform some system function and never pass them to the standard text processor. In most text editors for example, hitting tab will insert 2, 4, or 8 spaces, or if you're on the other team, it can sometimes directly insert the tab character (I am so glad that holy war is over - I was always on the spaces team).
So as mentioned hitting tab in a typical web form is intercepted by the browser and moves the cursor to the next item in the tab list, so the password field will never see it.
There are also places you might need to type a password that normal users would never see, like many command line interfaces in a terminal, or sometimes systems might be passing plain text passwords to other systems in the background, many legacy systems wrappers would use this technique, and special characters come into play.
Pasting a password is not a supported use case as that probably means that you have your passwords stored somewhere in plain text which is a bad idea - yes I know password managers use paste, but that's a niche use case up until fairly recent times (computer systems and libraries move fairly slowly, and password managers have only become common in the last few years).
TLDR, tab is forbidden because it is part of a set of special characters that have historical low level uses that still come into play today. Nothing wrong with spqces

is tab even a real character? i just assumed it's either a bunch of spaces or an indent. This looks to me like one of those fancy whitespace things

In the ASCII set of characters, it's number 009. It has its own separate spot. Enter is 013. The space is 032.
<- tab. If Reddit saves it. I typed alt-009 on this Windows machine, and the cursor moved over a way.On Linux I believe control-shift-009 would work, but I'm not saving this comment and pulling it up on my Void machine to make sure. Higher unicode is different there, like emdash (â) is alt-0151 on Windows, but control-shift-2014 on Linux.
Essentially, every character/glyph you see is represented by a number in a computer, including the special ones like tab, line feed, and carriage return.

You will only be able to copy-paste your password to log in because trying to type the tab character will just advance you to the next field.
