Frequently Asked Questions
Is this password generator safe and private?
Yes! 100% of password generation takes place locally inside your browser using JavaScript's cryptographically secure random number generator (Crypto API). No passwords are ever sent across the network or stored on any server.
What makes a password strong?
A strong password is long (at least 14-16 characters) and contains a mix of uppercase letters, lowercase letters, numbers, and special symbols. High length and character diversity increase mathematical entropy, making brute-force cracking practically impossible.
What are ambiguous characters?
Ambiguous characters are letters and numbers that look visually similar and are easy to misread, such as capital 'I', lowercase 'l', number '1', capital 'O', and number '0'. Checking 'Exclude Ambiguous' removes these for clearer readability.
How is the estimated crack time calculated?
Estimated crack time is calculated using Information Entropy formula (Length × log2(Pool Size)). We then calculate how long a high-speed supercomputer cluster (testing 100 billion guesses per second) would take to brute-force all possible combinations.
