Password Generator
Generate strong, random passwords instantly. All processing is done locally in your browser.
Generate multiple passwords at once using the same settings above.
About This Tool
This password generator uses the browser's built-in crypto.getRandomValues() API to produce cryptographically random passwords. Your passwords are never sent to any server. A strong password should be at least 12 characters long and include a mix of uppercase, lowercase, numbers, and symbols.
How to Generate a Strong Password
Set the password length using the slider. For most accounts, 16+ characters is recommended.
Choose which character sets to include. Using all four (uppercase, lowercase, numbers, symbols) creates the strongest passwords.
Enable "Exclude ambiguous characters" if you need to type the password manually (avoids confusion between 0, O, l, 1, I).
Click Copy and paste the password directly into your password manager or account form.
Frequently Asked Questions
How random are the generated passwords?
This generator uses the browser's built-in crypto.getRandomValues() API, which produces cryptographically secure random numbers. This is the same randomness standard used by security software and password managers.
What makes a password strong?
A strong password is long (12+ characters), uses a mix of character types, and does not contain dictionary words, names, or dates. Length is the most important factor — a 20-character all-lowercase password is stronger than an 8-character password with symbols.
Are my generated passwords saved anywhere?
No. All generation happens in your browser. Passwords are never transmitted to any server, never logged, and never stored. Once you close the tab, the password is gone.
Should I use a password manager?
Yes. Strong, unique passwords for every account are impossible to memorize. A password manager (like Bitwarden, 1Password, or KeePass) stores your passwords securely so you only need to remember one master password.
How long would it take to crack a 16-character password?
A random 16-character password using all character types has over 7 quadrillion possible combinations. At a trillion guesses per second, it would take millions of years to crack by brute force — making it effectively unbreakable with current technology.
