How long to crack a password

Firstly, 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.


The longer the password is, the more combinations there are to check and the more time this process takes.


Let's start with an easy one. 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 symbol, 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..


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 will 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. Whatever you choose, with our password generator and manager Passwarden creating and storing strong passwords is as easy as it gets.

Tips for creating a strong password

Use unique passwords


One of the issues about creating a strong password is having to memorize all of them. Of course, it’s easy to remember one strong password and use it for all accounts. But it is not a good idea at all. If your password is compromised, the attacker is likely to check if you use the same password on other services. 

We strongly recommend you to use unique passwords. Check out our comprehensive guide on how to remember dozens of strong passwords and keep hackers out of your data.

Use UPPERCASE, number5, and $ymbol$


As mentioned before, passwords that include special symbols, numbers, and uppercase letters are stronger than the usual ones. 

If you are not sure you can create a strong password by yourself, simply generate it using Passwarden. Our app allows you to specify password length, availability of symbols, numbers, and uppercase letters. Check out our app and see for yourself!

Avoid using personal information or common words


Personal information should stay personal. Be sure, cybercriminals will firstly try your name and birth date when attempting to crack your password. We highly recommend you to avoid using birthdays, names, or surnames of your family, friends, or pets.

Also, it’s better not to use common dictionary words. Try to use a random set of characters. It’s better to use a random 8 character password than a 16 character dictionary word. Not sure about your password’s strength? Get started with Passwarden and generate strong passwords in a minute!
