Dialogue: 0,0:00:10.84,0:00:12.68,Default,,0000,0000,0000,,And now, don't forget it.
Dialogue: 0,0:00:12.78,0:00:14.78,Default,,0000,0000,0000,,But never write it down!
Dialogue: 0,0:00:14.78,0:00:17.24,Default,,0000,0000,0000,,And please change it once a month of course.
Dialogue: 0,0:00:17.24,0:00:20.46,Default,,0000,0000,0000,,For every device and account a new one.
Dialogue: 0,0:00:20.46,0:00:25.02,Default,,0000,0000,0000,,Phew! Why does this "password thing" always have to be so complicated?
Dialogue: 0,0:00:25.02,0:00:29.52,Default,,0000,0000,0000,,How is it possible to come up with a password that is safe {\i1}and{\i0} easy to remember?
Dialogue: 0,0:00:29.52,0:00:32.80,Default,,0000,0000,0000,,For this purpose, it's good to understand how a password works
Dialogue: 0,0:00:32.80,0:00:34.80,Default,,0000,0000,0000,,and how it's cracked.
Dialogue: 0,0:00:34.80,0:00:38.82,Default,,0000,0000,0000,,You can imagine a password like the digits for a combination lock:
Dialogue: 0,0:00:38.82,0:00:41.68,Default,,0000,0000,0000,,And just like the digits here
Dialogue: 0,0:00:41.68,0:00:43.46,Default,,0000,0000,0000,,it's important that you don't use a combination
Dialogue: 0,0:00:43.46,0:00:46.44,Default,,0000,0000,0000,,that is easy to guess.
Dialogue: 0,0:00:46.44,0:00:47.36,Default,,0000,0000,0000,,Like your Birthday.
Dialogue: 0,0:00:47.36,0:00:49.76,Default,,0000,0000,0000,,Or the name of your friend, child, pet.
Dialogue: 0,0:00:49.76,0:00:53.28,Default,,0000,0000,0000,,Researching these on the web is quite easy.
Dialogue: 0,0:00:53.28,0:00:55.66,Default,,0000,0000,0000,,The big difference to a combination lock is
Dialogue: 0,0:00:55.66,0:00:59.68,Default,,0000,0000,0000,,that the hard work of trying combinations can be done by a computer.
Dialogue: 0,0:00:59.68,0:01:03.26,Default,,0000,0000,0000,,If a machine tries to guess your password online
Dialogue: 0,0:01:03.26,0:01:06.40,Default,,0000,0000,0000,,it hopefully get's blocked after a couple of tries.
Dialogue: 0,0:01:06.40,0:01:08.16,Default,,0000,0000,0000,,But if that's not the case,
Dialogue: 0,0:01:08.16,0:01:11.50,Default,,0000,0000,0000,,when a database gets stolen
Dialogue: 0,0:01:11.50,0:01:13.50,Default,,0000,0000,0000,,for example.
Dialogue: 0,0:01:13.50,0:01:17.24,Default,,0000,0000,0000,,The computer will have direct access to the lock.
Dialogue: 0,0:01:17.24,0:01:19.18,Default,,0000,0000,0000,,Then even an old notebook
Dialogue: 0,0:01:19.18,0:01:22.40,Default,,0000,0000,0000,,can try billions of passwords every second.
Dialogue: 0,0:01:22.40,0:01:26.24,Default,,0000,0000,0000,,And of course the attackers start with a list of the most frequently used passwords.
Dialogue: 0,0:01:26.24,0:01:29.62,Default,,0000,0000,0000,,And then try every single word in any language
Dialogue: 0,0:01:29.62,0:01:34.40,Default,,0000,0000,0000,,slang and with variations by using dictionaries
Dialogue: 0,0:01:34.40,0:01:36.88,Default,,0000,0000,0000,,and encyclopedias. That only takes a couple of seconds.
Dialogue: 0,0:01:36.88,0:01:39.34,Default,,0000,0000,0000,,This is the reason why you should use an
Dialogue: 0,0:01:39.34,0:01:42.10,Default,,0000,0000,0000,,"uncommon combination" of
Dialogue: 0,0:01:42.10,0:01:44.56,Default,,0000,0000,0000,,letters, numbers and special characters.
Dialogue: 0,0:01:44.56,0:01:47.04,Default,,0000,0000,0000,,Then the computer has to "manually"
Dialogue: 0,0:01:47.04,0:01:50.34,Default,,0000,0000,0000,,try out every single combination.
Dialogue: 0,0:01:50.34,0:01:55.70,Default,,0000,0000,0000,,This is called a "brute force attack".
Dialogue: 0,0:01:55.70,0:01:59.46,Default,,0000,0000,0000,,And if your password has 10 letters
Dialogue: 0,0:01:59.46,0:02:01.28,Default,,0000,0000,0000,,in only takes a couple of hours
Dialogue: 0,0:02:01.28,0:02:03.98,Default,,0000,0000,0000,,until the combinations is cracked.
Dialogue: 0,0:02:03.98,0:02:07.14,Default,,0000,0000,0000,,But if you just add one more letter
Dialogue: 0,0:02:07.14,0:02:09.60,Default,,0000,0000,0000,,it will take as long as twenty days.
Dialogue: 0,0:02:09.60,0:02:13.32,Default,,0000,0000,0000,,Because with every digit that you add, time increases exponentially.
Dialogue: 0,0:02:13.32,0:02:14.62,Default,,0000,0000,0000,,Five more digits
Dialogue: 0,0:02:14.62,0:02:19.46,Default,,0000,0000,0000,,and even ten computers need more than 2 400 years
Dialogue: 0,0:02:19.46,0:02:21.46,Default,,0000,0000,0000,,to crack your password.
Dialogue: 0,0:02:21.46,0:02:24.48,Default,,0000,0000,0000,,If you extend the "lock" also
Dialogue: 0,0:02:24.48,0:02:26.90,Default,,0000,0000,0000,,by making the "wheels" larger.
Dialogue: 0,0:02:26.90,0:02:29.58,Default,,0000,0000,0000,,By adding capital letters and numbers.
Dialogue: 0,0:02:29.58,0:02:33.36,Default,,0000,0000,0000,,Those ten computers would need around 1.1 billion years
Dialogue: 0,0:02:33.36,0:02:37.30,Default,,0000,0000,0000,,to crack a password with 15 digits.
Dialogue: 0,0:02:37.30,0:02:39.06,Default,,0000,0000,0000,,Unfortunately
Dialogue: 0,0:02:39.06,0:02:44.30,Default,,0000,0000,0000,,"nzb6Xrtc57l1mnk"
Dialogue: 0,0:02:44.30,0:02:46.60,Default,,0000,0000,0000,,is so hard to remember.
Dialogue: 0,0:02:46.60,0:02:48.40,Default,,0000,0000,0000,,That's why it's helpful
Dialogue: 0,0:02:48.40,0:02:50.60,Default,,0000,0000,0000,,to think of a "passphrase"
Dialogue: 0,0:02:50.60,0:02:53.44,Default,,0000,0000,0000,,instead of a pass{\i1}word{\i0}.
Dialogue: 0,0:02:53.44,0:02:55.90,Default,,0000,0000,0000,,Because phrases are easier to remember -
Dialogue: 0,0:02:55.90,0:02:59.54,Default,,0000,0000,0000,,and usually longer than words.
Dialogue: 0,0:02:59.54,0:03:00.92,Default,,0000,0000,0000,,For example
Dialogue: 0,0:03:00.92,0:03:05.72,Default,,0000,0000,0000,,"30dividedby10=Three"
Dialogue: 0,0:03:05.72,0:03:06.82,Default,,0000,0000,0000,,or:
Dialogue: 0,0:03:06.82,0:03:13.86,Default,,0000,0000,0000,,"A Passphrase features more security > a Password"
Dialogue: 0,0:03:13.86,0:03:15.60,Default,,0000,0000,0000,,or simply:
Dialogue: 0,0:03:15.60,0:03:20.54,Default,,0000,0000,0000,,"This is my Passphrase for E-Mails".
Dialogue: 0,0:03:20.54,0:03:23.00,Default,,0000,0000,0000,,With these you will have more than 15 digits
Dialogue: 0,0:03:23.00,0:03:24.72,Default,,0000,0000,0000,,small and capital letters
Dialogue: 0,0:03:24.72,0:03:27.60,Default,,0000,0000,0000,,and in most cases even special characters.
Dialogue: 0,0:03:27.60,0:03:30.60,Default,,0000,0000,0000,,Cracking such a passphrase with "brute force"
Dialogue: 0,0:03:30.60,0:03:33.48,Default,,0000,0000,0000,,takes atleast a couple of thousand years.
Dialogue: 0,0:03:33.48,0:03:37.30,Default,,0000,0000,0000,,Yet you can easily remember it.
Dialogue: 0,0:03:38.42,0:03:43.82,Default,,0000,0000,0000,,Alright. Have fun coming up with your own phrases ;-)
Dialogue: 0,0:03:43.82,0:03:48.62,Default,,0000,0000,0000,,Because you shouldn't use the examples from this video
Dialogue: 0,0:03:48.62,0:03:50.62,Default,,0000,0000,0000,,alright... that's enough.
Dialogue: 0,0:03:50.62,0:03:52.62,Default,,0000,0000,0000,,It's enough.
Dialogue: 0,0:03:52.62,0:03:55.18,Default,,0000,0000,0000,,Thank you for watching.
Dialogue: 0,0:03:55.18,0:03:58.44,Default,,0000,0000,0000,,You can find more info and references
Dialogue: 0,0:03:58.44,0:04:01.48,Default,,0000,0000,0000,,concerning passphrases
Dialogue: 0,0:04:01.54,0:04:05.00,Default,,0000,0000,0000,,in the video description.
Dialogue: 0,0:04:07.00,0:04:09.36,Default,,0000,0000,0000,,I will stop talking now.
