All cool and dandy, until you have to type that random 50 letter string on your TV.
Many PW managers let you generate passphrases, which are all around better than random strings. Length is the most important factor so
finance-caffeine-utopia-redress-unseen
Is way stronger and easier to remember (and type) than
Fl7$j4FWw)&5O
Is it really safer? I mean when trying to bruteforce a password, one would have to make a guess whether it’s a passphrase or not. But if you decided to check for pass phrases, wouldn’t the one you posted be cracked in 5 times the amount of words in that dictionary? I’m not sure how large the vocabularies of the generators are, but I would guess a random 17 char password might be safer than a 5 phrases password?
but I would guess a random 17 char password might be safer than a 5 phrases password
And you would be very wrong about that. A 5 phrase password has entropy. “finance-caffeine-utopia-redress-unseen” is 28 characters. If you add in a different symbol between the words and add a number somewhere, this password becomes incredibly difficult to brute force.
I’ll let xkcd explain it better.
You don’t need to make it that long.
And also most TVs or whatever you’re streaming with has a way to type from your phone nowadays. Apple TV, Chromecast, Android TV, heck I think even Xbox.
It’s kinda nice on Apple TV your phone will suggest autofill passwords for the TV, even from theirs party password managers like Bitwarden.
Android tv’s arent that old. 10 years max. 5 years since it’s affordable for most people. Is it unreasonable to own a 5 year old non-smart tv? I think not. I think it’s weird that so many people assume everyone owns a smart tv.
For symmetric keys, since they cannot be weakened using quantum computing, their strength can be assessed by their bit-equivalent amount of entropy:
- 40 bit or less - easily breakable
- 64 bit - not so easy, but doable
- 128 bit or more - basically unbreakable
Those are equivalent to, respectively:
- 0-9 - 12, 19, 38 characters
- a-z - 9, 14, 28 characters
- a-z0-9 - 8, 12, 25 characters
- A-Za-z0-9 - 7, 11, 22 characters
- A-Za-z0-9+special - 7, 10, 21 characters
Moral of the story: drop the special characters, and even the numbers… and even the uppercase. A 30+ character long all-lowercase pass phrase, is already unbreakable.
Check @falsemirror@beehaw.org:
finance-caffeine-utopia-redress
-unseen
…is already over 128 bits.
