Password Generator
Click "Generate" to create a password
A strong password is your first line of defense against unauthorized access. This generator offers two modes: "Random" creates a cryptographically strong password using the browser's built-in secure random number generator, and "From keyword" transforms your memorable word into a strong password using leet-speak substitutions, capitalization rules, and symbol additions — giving you a password that's both strong and easier to remember.
Frequently Asked Questions
Is this password generator secure?
Yes. In "Random" mode, passwords are generated using the Web Cryptography API (crypto.getRandomValues), which is cryptographically secure. No passwords are sent to any server — all generation happens locally in your browser.
What is the "From keyword" mode?
You enter a word (e.g. "sunshine") and the generator applies leet-speak substitutions (e→3, a→4, o→0, etc.), capitalization, and adds symbols and numbers to create a strong password. The same keyword always produces the same password, making it predictable for you but secure against brute-force.
How long should a password be?
At least 12 characters for most accounts. For critical accounts (banking, email, primary passwords), use 16+ characters. Longer passwords are exponentially harder to crack even without special characters.
Should I include symbols in my password?
Yes, if the site allows it. Symbols dramatically increase the number of possible combinations. A 12-character password with symbols has roughly 10,000× more possible combinations than one with lowercase letters only.
What is a strong password?
A strong password is at least 12 characters long, contains a mix of uppercase and lowercase letters, numbers, and symbols, and is not based on dictionary words, personal information, or predictable patterns like "Password123!".
