When you create a password for your online account, you may think the most important thing is to make it as long as possible. But this is not necessarily the case.
In fact, strong passwords are not even in the top three factors that affect how hard it is to crack them. The number one factor is how many characters it has followed by how random they are and whether they include lowercase and uppercase letters, numbers, and symbols.
In other words, hackers don’t need to know your name or where you live to find out what your password is. They can use a program called a brute force attack which tries every combination of letters, numbers, and symbols to crack a password.
There are two main ways websites store passwords: either in plain text (i.e., unencrypted) or encrypted with an algorithm like SHA-1 or MD5 (a type of encryption).
If your website stores passwords in plain text then anyone who gets hold of them will be able to see them immediately. If they’re encrypted then only someone with access to the encryption key would be able to see them or use software to crack password security.
What is Brute Forcing?
The term “brute force” refers to a method of attempting many different keys until the correct one is found. It is a form of cryptanalysis that does not use any knowledge about the key but simply tries all possible keys until the right one is found.
The classic example of a brute force attack is trying all possible combinations of numbers or letters for cracking passwords.
What Is Brute Forcing a Password?
Brute forcing a password means trying every possible combination until you get it right. This can be done by hand with pencil and paper, but it would take forever if you tried every single possibility (a typical 8-digit numeric PIN has only 10,000 combinations).
A computer attack is much faster because there are tools that can try thousands or even millions of combinations per second (depending on how fast your computer is).
Brute forcing is an attack that tries all possible combinations of characters in order to find out the correct one. The attacker tries every character combination from A to Z, from 1 to 25, and so on until he finds the right password.
This type of attack is called a “dictionary” attack because it uses an encryption dictionary made up of millions of passwords.
How long does it take to crack a password using a brute force algorithm?
It is a well-known fact that using brute force is one of the most popular ways to crack passwords. However, it requires high-end hardware and software as well as a lot of time. It is possible only if you have enough resources and don’t mind waiting for results.
Let’s take a look at some examples:
If you want to crack six or fewer characters long passwords (lowercase letters), then it will take about 0.19 milliseconds per password. So if your computer can perform 1 billion calculations per second (1 GigaFLOPS), then it will take about 19 hours to crack all possible combinations of lowercase letters in 8-character length passwords (not including the time needed for loading data into memory).
If we look at uppercase letters in 8-character length passwords, then it will take about 0.04 milliseconds per password. So if your computer can perform 1 billion calculations per second (1 GigaFLOPS), then it will take about 4 hours to crack all possible combinations of uppercase letters in 8-character length passwords (not including the time needed for loading data into memory).
Type of brute force attack
Dictionary attack: This type of attack uses an existing dictionary with words that are known to be in use as passwords, such as a dictionary or thesaurus. The attacker uses a program to try to log into the system with each word in the dictionary.
This is one of the least effective ways to break into a system or online accounts, but it’s also one of the easiest and cheapest.
Hybrid attack: This type of attack combines two or more methods, for example using brute force along with a dictionary. Hybrid attacks are effective at bypassing password complexity rules that prevent dictionary and brute-force attacks from being used.
List the best way to prevent brute force attacks
Use a strong password. Use at least 14 characters and include uppercase, and lowercase letters, numbers, and symbols. Don’t use dictionary words or names, since hackers often try those first. You can use a password manager like LastPass or KeePass to help you create strong passwords for all your accounts.
Use two-factor authentication (2FA) when available. 2FA requires the user to enter a code sent to their phone before they can log in. It’s more secure than using just a password alone because even if someone knows your password, they still can’t get into your account without access to your phone too.
Enable login notifications on all accounts that support them. This alerts you when someone tries logging into your account from an unrecognized device or location so you can take action right away if necessary instead of waiting for the attacker’s next move later on down the road.
Enable multi-factor authentication (MFA) when available. MFA requires a user to enter not just a password but also another piece of information that only they have access to, such as their fingerprint or a one-time code sent to their phone.
This is more secure than using just a password alone because it makes it harder for someone to get into your account even if they know your password manager.
What is a good length for a password?
It is generally suggested to use 8-character passwords for storing a password. A minimum number of passwords is not possible at this time. Providing adequate protection against brute force attacks is regarded as extremely important. Good password strength can prevent a data breach and a common password will give hackers an easy time cracking your password.
Asci, lowercase, and numeric characters
Combining multiple character types will help you create a cryptic password. Simple words are broken in seconds by a simple number. Insert lowercase letters, numbers, and symbols and your login password will remain safe for up to 10 years.
Alpha and number characters
Combining numbers and letters instead of using just the same character drastically improves password protection. A 9-digit string takes milliseconds to crack. Add one letter to your password.
It’s likely that this is cryptic enough to taint your passwords for nearly forty years. Adding an “e” to a letter can be difficult. Attacks on passwords use the same basic behavior in many cases. You should make passwords less predictable.
How long does it take to crack passwords by length?
The length of your password is only one factor in how long it will take to crack. The other factors are the complexity and entropy of your password.
Complexity means that you have used a mix of upper and lower case letters, numbers, and symbols in your passwords. Entropy is how many possible combinations there are for a given length of the password.
If you have a seven-digit password with just numbers, it will be cracked in seconds. But if you use upper case letters, lower case letters, numbers, and symbols in your password, it could take many hours or even days for an attacker to crack it.
The longer the password is, the more difficult it is to crack by brute force methods. For example:
One seven-digit password could be smashed within a matter of seconds, while another containing dozens of characters might be smashed within seconds. Shorter passwords with a simple letter would only require minutes of cracking but longer passwords using mixed case letters would take weeks or months to crack depending on the system being attacked.
What are character password examples?
Passphrases should contain four characters: upper and lowercase. Uppercase: a-z. Number: 10-9… Password Advice. $ a s 5. @ or A for the a.7 or t for the 3r. or e for e.9, G or 6. $ – s – five for the s. i. or. i.. = and A for A. 8 for the t. 2 or. 9, A or 6 to A. No. If ok. 7. or A in B.
password difficulty chart
This chart shows the time it would take to crack a password, based on its length and complexity.
- An 8-character password has about 6 characters in common with every other 8-character password.
- A 4-character password has about 3 characters in common with every other 4-character password.
- A 2-character password has about 1 character in common with every other 2-character password.
How to use a password manager
How to use a password manager for password security, brute force attack method, strong passwords, stolen passwords, password length, complex passwords, multiple sites to save your password
A good password manager will make it easy for you to create and store strong, unique passwords for all of your accounts. It will also provide a way for you to quickly create complex passwords that are difficult to crack.
Here is how you can use a password manager:
Use a strong master password. A strong master password should be at least 12 characters long and contain a mixture of numbers, letters, and symbols. It should not be related to any personal information about you or your family members. If possible, don’t use dictionary words or names in your master password as they are easily guessed by hackers using brute force attacks.
Create different passwords for each site that requires one. This will make it harder for hackers if they gain access to one of your accounts because they won’t be able to access any others with that information alone. Some websites even allow you to save multiple user names with the same email address so that you don’t have to remember them all if they’re all in the same format (e.g., “UserName@YourDomain.com”). Don’t use the same password for every website you visit. If your password is compromised, hackers will have access to all of your accounts—not just one or two.
How long should my password be?
The passwords are simple – size matters. The addition of an additional digit for a password increases security exponentially. A forensics program is designed to identify a common username for any given user and identify it using a list of common passwords. This list demonstrates the advantages of using characters in an encrypted database. A typical seven-character password is broken in ten milliseconds. Add one more character (abbcdefgh). Eventually, the duration reaches five hours.
