I’m aware of what constitutes a decent password, but typing in 15-30 random characters each time I lock my computer screen is starting to get a bit taxing.
How secure does my user password really need to be and what are the threats to it? Does the same apply to a root-enabled user as a “regular” user when it comes to password security?
For context, my threat model doesn’t need to account for real people breaking in and accessing my computer, the damage would be very contained.
Bonus question - what are the risks of having a weak password on a root user on a spare laptop on the same network as my main device that is used exclusively for web browsing? Thanks.
Not a direct answer to your question, but you can use passphrases instead to make it easier and faster to type. This is assuming your only option to log on to your computer and unlock your screen is to type in your password (e.g. no biometrics or hardware token options).
Using random characters is dumb.
It incetivices you to write it down (which in and of itself isn’t a completely terrible idea).
As an IT guy, let me tell you, STOP using random passwords!
Use passphrases instead, it is far easier to remember a sentence than a random string of letters and numbers.
Agreed - the message I was trying to convey is that I use a very secure password, which sacrifices convenience for security - is this necessary though? I have no concerns related to memorising or particular difficulties typing it out as it follows a passphrase structure for the most part.
One can also mix in numbers and symbols and capital letters with their passphrase / sentence. Throw in a comma, exclamation mark, replace an l with 1, o with 0, etc. of course it’s diminishing returns with a sufficiently long passphrase but it can help against dictionary type attacks by adding additional mutations / steps to the cracking.
Years ago I worked at a company where they based server root/admin passwords on song lyrics. The person who came up with it clearly liked classic rock. I still remember at least one of them:
4ThoseAboutToRockWeSaluteYou!
Lyrics are a pretty good base. Especially in passphrase style with spaces if supported, along with punctuation and capitals/numbers. What sucks is when an account system can’t support a long password. That’s the most frustrating requirement for any service and the greatest vulnerability of all the common restrictions.
Yeah, but you still need a password you can remember to unlock the password manager
Yeah that’s my preferred method too. Bitwarden’s password generator can create passphrases too, so I have it just create random ones for pretty much everything. The only ones I have to remember are the ones to unlock Bitwarden itself, and the one to unlock the decryption when I boot my PC up. So like two sentences essentially. I literally don’t even know what the passwords are to anything else lol.
I just memorize 8 characters of gibberish. It is fast to type in.
I have also used a hybrid approach which is 2-3 words with ransom numbers and symbols
“nobody can crack this password in a million years” in pretty strong
Edit :
“nobody can crack this password in a million years with current technology”
This is an interesting table for password cracking based on password hash…
I was wondering why 1 year was in the red category, but then I realized that that time could decrease quite a bit over time with technological advances
EDIT: typo
To address the “why”:
A user account, as defined by a username/password combination, can be used to access resources on the machine without logging in interactively on that machine. In a perfect world, you would only ever log in interactively on the machine using an account with restricted permissions, and when you needed to do “administraty” things, you would provide separate admin credentials at that time (sudo, runas, whatever your OS of choice supports).
Bonus question - what are the risks of having a weak password on a root user on a spare laptop on the same network as my main device that is used exclusively for web browsing?
If someone is able to compromise that root user on Machine A, then they may be able to leverage Machine A as a platform to attack any other devices on your network, or make Machine A into a zombie in their bot army to attack other targets anywhere, send spam, whatever malicious shenanigans they desire. (I know that’s pretty simplistic, there’s a whole lot of details left out, but that’s the gist of it.)
Also, nobody has yet mentioned the PIN option. I know that Windows machines (at least some of them, depending on configuration) allow you to configure a PIN for logon for local accounts. This PIN is only stored locally on the machine, and is not transmitted anywhere else. It’s basically a “shortcut” to the full password, and I think it can only be used for interactive logon.
Just like a chain, strength is determined by the weakest link
Use secure passphrase for ALL your devices on your network
I guess my question is why so? How vulnerable are my devices with a compromised device on the network?
