About Password Strength
Password strength is a measure of how effectively a password resists guessing and brute-force attacks. Strong passwords are essential for protecting your online accounts from unauthorized access and identity theft.
How Password Strength is Calculated
Our password strength checker evaluates your password based on several factors:
- Length: Longer passwords are exponentially harder to crack
- Complexity: Use of different character types (uppercase, lowercase, numbers, symbols)
- Unpredictability: Avoidance of common words, patterns, or personal information
- Uniqueness: Not found in common password databases or dictionaries
Password Strength Levels
Passwords are classified into five strength levels:
- Very Weak: Easily guessed in seconds (e.g., "password", "123456")
- Weak: Can be cracked in minutes to hours (e.g., "Password1")
- Medium: May take days to weeks to crack (e.g., "P@ssword123")
- Strong: Could take years to crack (e.g., "J7$k9Lm2#pQ")
- Very Strong: Virtually uncrackable with current technology (e.g., "xK8$qL2#mN5*pR9!")
Time to Crack Estimates
The estimated time to crack your password is based on:
- Brute-force attacks: Trying all possible combinations
- Dictionary attacks: Trying common words and variations
- Hybrid attacks: Combining dictionary words with random characters
These estimates assume an attacker using modern hardware capable of testing billions of passwords per second.
Creating Strong Passwords
Follow these best practices for creating secure passwords:
- Use passphrases (e.g., "CorrectHorseBatteryStaple") instead of single words
- Make passwords at least 12 characters long
- Include a mix of character types
- Avoid personal information (names, birthdays, etc.)
- Don't reuse passwords across different accounts
- Consider using a password manager to generate and store strong passwords
Note: No password is completely uncrackable, but strong passwords make it impractical for attackers to gain access to your accounts.
