Comment on My password is not accepted because it is too long

There is little point of having a long password. Online accounts don’t have the same issues as encryption
That’s simply false. Increased length increases the entropy of a password, making it harder to brute force to gain access.
You have to go out of your way to restrict the length of passwords. There’s absolutely no reason to do it, and it is contrary to all good security practices.
I’m not sure how you expect someone to brute force a web service. It is possible but it would be equivalent to a denial of service. Having long passwords for a online login makes no sense. A randomly generated 12 character password isn’t any more or less secure than a 40 character password since they both take a unrealistic amount of time to brute force.
A 12 character password made up of standard characters would take 475,920,314,814,253,376,475,136 tries assuming you know the length. I don’t see how someone could brute force a web service.
I will say I get annoyed at web services that require special characters since I like to use 3 words from the EFF extended word list.
how braindead are you?
How old are you?
The old security wisdom has been thrown out in favor of better practices. If you spend to much time focusing on one spot you will make everyone hate you while leaving gapping holes in your security.
your comments just make me hope that you never touch an IT system as a developer

I love wordlists
Think of it from a random guess perspective. Guessing a number randomly generated between 0-16 is easier than guessing one between 0-8.
Now think that all passwords are stored in certain amount of bits, so let’s compare 4 and 8 bits.
Each bit has a chance to be either 0 or 1, so guessing a single bit’s possibility is 1/2.
Guessing the correct orientation of 4 different bits takes 1/2^4^ = 1/16 Guessing the correct orientation of 8 different bits takes 1/2^8^ = 1/256
At a certain point it doesn’t matter as the password is effectively unguessable.
One weakness with longer passwords is that if they are created by humans chances are it will be easier to guess the pattern. This is true for all human created passwords but I think the longer ones are worse since there is more space to create a easily guessable pattern.
Assuming a breach, and hashes are released, its significantly harder to bruteforce a long password.
Some (a lot) poorly set up websites may not even have a limit on password attempts, or cooldowns.
It won’t matter if you use a password manager. You shouldn’t rely on the website to keep your password safe. They could be storing it in plain text for all you know. (It has happened before)
pls elaborate
As long as the adversary doesn’t have the ability to brute force the password locally, you have the ability to reset in the event of a leaked hash and you aren’t reusing passwords you are fine with a shorter password. Obviously be mindful of easily guessable passwords or ones that are very short. However, a 12 computer generated password is fine.

you realize that they say the exact opposite of what you are saying, right?

You haven’t provided any evidence to support your claim. Online accounts can’t easily be brute forced.
If a hash is leaked you just change the password. As long as you aren’t reusing the same password everywhere you are fine.

If the hashes are leaked and that’s immediately caught and customers are immediately informed, just change your password.

How do you know when a password is leaked?
What’s the distribution of variance in brute force protections on online services?
possiblylinux127@lemmy.zip 2 months ago
Why would it matter? If they can access the password they probably can access everything else on that service. Just don’t reuse passwords.
