A general rule is that your password should be at least 11 characters and use numbers, along with upper and lowercase letters. That combination will take hackers 41 years to crack. But what about passwords that use the full gamut of password creation?

Are passwords difficult to crack?
The more you mix up letters (upper-case and lower-case), numbers, and symbols, the more potent your password is, and the harder it is for a brute force attack to crack it. Avoid common substitutions.
How long would it take to brute force a 100 character password?
At 50 attempts/second, this would take about 100,000 years to break. However, this is only true if the password is composed of a random set of symbols. If, for example, you use the word “password” for a password, it will be broken almost at once, in spite of having 8 letters. Size matters.
How long would it take a supercomputer to crack my password?
Using a GPU processor that tries 10.3 billion hashes per second, cracking the password would take approximately 526 years. Although, a supercomputer could crack it within a few weeks. By this logic, including more characters makes your password even harder to solve.
Why Longer passwords are harder to break?
The longer the password, the longer it will take to crack. When a password cracker has more characters to fill to guess the correct password, it’s exponentially less likely to get it right. In other words, you don’t need a complex password with lots of fancy special characters if you have a long password.
What is the hardest password to hack?
Top 5 Strongest Password
- Mix meanless Word, number and symbol randomly, and at least 15 length.
- Mix Word and number together randomly.
- Replace Word with number and symbol randomly.
- Combine word with number.
- Combine partial unrelated words together.
How long does it take to crack a 4 digit PIN?
It would take up to 112 hours to brute force a 4 digit PIN, because each PIN entry takes 40 seconds.
How long would it take to crack a 8 digit password?
With traditional CPU password cracking, it would take around 92 years to guess all of the iterations using uppercase, lowercase and numbers for an 8 character password. For the same possible combinations, it takes a moderately architected GPU cracker just seven minutes.
How long does it take to crack a 6 digit PIN?
According to calculations and articles you will find online, a six digit passcode takes up to 22.2 hours to break, while processing an 8-digit code can take as few as 46 hours or up to 92 days.
How long does it take to crack a 10 digit PIN?
Since there are 10^10 (ten billion!) possible numeric passwords, it would take a randomized brute force attack ten billion seconds (317 years) to try all of them. On average an attack would take half that long … about 158 years using one computer.
What are the 5 most common passwords?
Frequently used passwords in the U.S.

- 1234567.
How fast can brute force?
Recent computers manufactured within the last 10ish years can brute force crack an 8 character alphanumeric password – capitals and lowercase letters, numbers, and special characters – in about two hours. Computers are so fast that they can brute force decrypt a weak encryption hash in mere months.
Can a password be too long?
Microsoft imposes a length limit on the passwords its customers create: passwords can include a mix of upper and lower case letters, numbers, and symbols, but they can be no longer than 16 and no shorter than eight characters.
How long should a good password?
“A longer password is usually better than a more random password,” says Mark Burnett, author of Perfect Passwords, “as long as the password is at least 12-15 characters long.”
Do longer passwords make us safer?
Therefore, a lengthy list of easy-to-remember words or a passphrase could be actually more secure than a shorter list of random characters. Lengthy passwords made of actual words are definitely easier to remember and could help users manage them in more secure way.
How long can passwords be?
Strong passwords are longer than eight characters, are hard to guess and contain a variety of characters, numbers and special symbols. The best ones can be difficult to remember, especially if you’re using a distinct login for every site (which is recommended). This is where password managers come in.
What are the safest passwords?
Do use a combination of uppercase and lowercase letters, symbols and numbers. Don’t use commonly used passwords such as 123456, the word “password,” “qwerty”, “111111”, or a word like, “monkey”. Do make sure your user passwords are at least eight characters long.
What is the best password in the world?
Here are the main traits of a reliable, secure password:
- At least 12 characters long (the longer, the better).
- Has a combination of upper and lowercase letters, numbers, punctuation, and special symbols.
- Random and unique.
How long does it take John the Ripper to crack a password?
“Single crack” mode runs typically take from under a second to one day (depending on the type and number of password hashes).
How long would it take to crack a 12 digit PIN?
Nine-character passwords take five days to break, 10-character words take four months, and 11-character passwords take 10 years. Make it up to 12 characters, and you’re looking at 200 years’ worth of security – not bad for one little letter.
How hard is it to brute force a 4 digit PIN?
As such, each PIN entry takes approximately 40 seconds, meaning that it would take up to ~111 hours to bruteforce a 4 digit PIN.A four digit PIN code is never going to be as strong at protecting your iPhone or iPad as a longer, hard-to-guess password.
