Question 1

Is this password generator secure?

Accepted Answer

Yes. It uses the Web Crypto API (crypto.getRandomValues) for cryptographically secure randomness. The password is generated entirely in your browser — nothing is sent to any server, stored in any database, or logged anywhere.

Question 2

How long should my password be?

Accepted Answer

We recommend at least 16 characters with a mix of uppercase, lowercase, numbers, and symbols. This provides roughly 105 bits of entropy — effectively uncrackable by brute force. For master passwords or high-security accounts, use 24-32 characters.

Question 3

What does the strength meter show?

Accepted Answer

The strength meter calculates entropy — a measure of how many possible combinations an attacker would need to try. Higher entropy means a stronger password. We rate passwords as Weak, Fair, Strong, or Very Strong based on their bit count.
