How long it takes to brute force a password

Let’s figure out how long it takes to crack or brute-force different passwords depending on their length, character types, and letter case.

So that we’re on the same page, brute-force attack or brute force cracking is a cryptographic hack that relies on submitting all possible password combinations until the correct one is discovered.

Now guess how long it takes to crack an 8 character password, for example, “password”? You know, the answer may surprise you - 0.19 milliseconds. For comparison, the duration of blinking is on average 100–150 milliseconds.

Combining several types of characters (lowercase and uppercase letters, digits, and special symbols) is an extremely effective way to make your password stronger and increase the cracking time from milliseconds to millennia.

The maximum time it would take to crack the password “Password123” equals 41 years. If you add “/” or any other special character, this time increases to 63 thousand years. Impressive, isn't it?

Fun fact: It would take a computer about 7 quadrillion years to crack the password [email protected][email protected]!”  It could be a good example of a strong password… If only we didn’t make it available for everyone to see… Oops...

But, what is more efficient, a short password that combines several types of characters or a long one that consists of letters only? Let’s get this over with!

  8 characters password 10 characters password 12 characters password
Lowercase letters only instantly instantly several weeks
+ 1 uppercase letter half an hour 1 month 5 years
+ 1 number one hour 6 years 2 thousand years
+ 1 special symbol one day 50 years 63 thousand years

It becomes obvious that the longer the password is, the more combinations there are to check and the more time this process takes. Thus, it makes sense to create long passwords. However, we highly recommend you not to neglect password strength and still use different types of characters.

It is also worth mentioning Moore's law. It states that the CPU and GPU double in speed and capability about every two years. Thus, the time to crack a password is also halved. It means that it would take 12 decades today, it would take 6 decades in 18 months, 3 decades in 36 months, and so on.

  Now In 10 years In 20 years
password 0.19 milliseconds 0.0059375 milliseconds instantly
Password123 41 years 1 year 3 month 10 days 20 days
Password123/ 63 millennia 1 millennium 970 years 61 years 6 month 20 days

That’s why you should set up strong and unique passwords and change them from time to time. The recommended frequency of password changes ranges from every 30-90 days to every 1-2 years.

How to create a strong password

As it was mentioned before, it’s better to create long passwords with different types of characters. But that is not the only rule you should follow.

For instance, the password “John-1984” has 9 characters and consists of uppercase and lowercase letters, digits, and special symbols. But it isn’t strong enough, because it contains personal information.
