Generate Strong Password
Why Strong Passwords Matter
In 2024, a weak password is an open invitation. Brute-force attacks, where attackers use automated software to guess millions of passwords per second, are more common than ever. A password like "123456" can be cracked instantly.
A strong, complex password increases the "entropy," or randomness, making it exponentially harder for these tools to guess. A 12-character password with letters, numbers, and symbols could take centuries to crack, while an 8-character password with only letters could take just hours.
This tool helps you visualize that strength and build a better digital fortress.
How Our Scoring Works
We don't just check boxes. Our algorithm calculates a "strength score" based on multiple factors to give you a realistic assessment:
- Length (Weight: 40%): The most critical factor. We award significant points for every character, especially after 8 and 12.
- Character Variety (Weight: 60%): We check for four distinct types of characters:
- Uppercase Letters (A-Z)
- Lowercase Letters (a-z)
- Numbers (0-9)
- Special Symbols (!@#$%^&*)
The score is a combination of these elements, capped at 100. A "Very Strong" password (90+) has high length and all four character types, making it highly resistant to modern attacks.
