Password Strength Checker

About Password Strength Checker Tool

The Password Strength Checker tool analyzes your password and provides feedback on its security level. It evaluates several criteria including length, character variety, and common patterns to determine how resistant your password would be against various hacking attempts.

This tool runs entirely in your browser - your password is never transmitted over the internet or stored anywhere. For maximum security, avoid checking passwords for accounts you currently use on public or shared computers.

How Password Strength is Measured

The strength of a password is determined by several factors:

• Length: Longer passwords are generally more secure. A minimum of 8 characters is recommended, but 12 or more is ideal.
• Complexity: Including a mix of uppercase letters, lowercase letters, numbers, and special characters significantly increases password strength.
• Unpredictability: Avoiding common words, patterns (like “123456”), and personal information makes passwords harder to guess.
• Uniqueness: Using different passwords for different accounts prevents multiple account compromises if one password is exposed.

Common Password Vulnerabilities

• Dictionary Words: Passwords that are common words or phrases are easily cracked using dictionary attacks.
• Personal Information: Using birthdays, names, or other personal details makes passwords predictable.
• Character Substitution: Simple substitutions (like “p@ssw0rd”) are well-known patterns that password cracking tools can easily detect.
• Keyboard Patterns: Sequences like “qwerty” or “12345” are among the first combinations attackers try.
• Password Reuse: Using the same password across multiple sites means one breach can compromise multiple accounts.

Creating Better Passwords

• Use random combinations of characters rather than meaningful words.
• Consider using a passphrase (a sequence of random words) for better memorability and security.
• Use a password manager to generate and store strong, unique passwords for each account.
• Enable two-factor authentication (2FA) wherever possible as an extra security layer.
• Change passwords periodically, especially for critical accounts.
