Test your password strength and get personalized security tips
Password GeneratorPassword security is crucial in today's digital world where data breaches and cyberattacks are increasingly common. A strong password is your first line of defense against unauthorized access to your accounts and personal information.
Understanding how attackers try to crack passwords can help you create stronger ones. Here are the most common password attack methods:
Attackers use automated tools to try every possible combination of characters until they find the correct password. The time required depends on the password's length and complexity. A longer password with more character types exponentially increases the number of possible combinations, making brute force attacks impractical.
Instead of trying all possible combinations, dictionary attacks use lists of common words, phrases, and known passwords from data breaches. This method is much faster than brute force for cracking passwords based on real words or common patterns. Adding numbers or special characters to dictionary words (like "password123!") often isn't enough to protect against sophisticated dictionary attacks.
When data breaches occur, attackers obtain lists of email/username and password combinations. They then automatically try these credentials on other websites, exploiting the fact that many people reuse the same passwords across multiple sites. Using unique passwords for each account protects you from this attack.
Attackers may use information available about you online (from social media or other sources) to guess your password or answer security questions. Avoid using easily discoverable information like birthdates, anniversaries, children's or pet's names, or other personal details in your passwords.
These are precomputed tables for reversing cryptographic hash functions used to store passwords. Attackers use these tables to find passwords from stolen hash values. Modern systems use "salting" (adding random data to each password before hashing) to defend against this, but using complex passwords provides additional protection.
Yes, our password strength checker operates entirely in your browser. Your password is never sent to our servers or stored anywhere. The analysis happens locally on your device for complete privacy and security.
Our tool analyzes various aspects of your password including length, character types, common patterns, and predictability. It uses mathematical models to estimate how long it would take for a hacker to crack your password using different attack methods.
A strong password typically has 12+ characters, uses a mix of uppercase letters, lowercase letters, numbers, and special characters, avoids common words or patterns, and is unique (not used on multiple websites).
Our crack time estimations are based on current average computing power and known password cracking techniques. They represent reasonable estimates but actual times may vary based on the attacker's resources and methodology.
Yes, we strongly recommend changing any passwords that are rated as weak or very weak, especially for important accounts like email, banking, or social media. Use our password generator tool to create strong replacements.
Password length has a more significant impact on security than complexity alone. Each additional character exponentially increases the number of possible combinations an attacker would need to try. A 16-character password with only lowercase letters is often stronger than an 8-character password with mixed character types.
The best solution is to use a password manager, which can store all your complex passwords securely. You only need to remember one master password. Alternatively, you can create memorable passphrases by combining several random words with numbers and symbols.
