Password Strength Checker

Evaluate the strength of entered passwords. Strength is evaluated based on password length, character types, and usage patterns.

Very Weak: Can be cracked immediately. Never use this.

Weak: Can be cracked relatively easily. Improvement needed.

Medium: Sufficient for general use, but improvement recommended for important accounts.

Strong: Difficult to crack and suitable for most purposes.

Very Strong: Extremely difficult to crack and suitable for the most important accounts.

Use at least 12 characters for your password. Longer passwords are much harder to crack.

Include uppercase letters, lowercase letters, numbers, and special characters (!@#$%^&*, etc.) to significantly improve password complexity.

Passphrases combining words with numbers and special characters are memorable yet secure. Example: Blue-Horse-Battery-Staple-42!

Instead of reusing the same password across different sites, use a password manager to generate and manage complex passwords.

Update passwords for important accounts regularly. Change them immediately if there's a possibility of data breach.
