How to Generate Strong, Secure Passwords Online for Free
Creating new login credentials, API secrets, or Wi-Fi passwords? BrowserPowerToys generates mathematically random passwords using your browser's hardware-backed Web Crypto API (crypto.getRandomValues). Passwords exist exclusively in temporary memory on your device with zero server logging or tracking.
Set Password Length
Adjust the length slider from 8 up to 64 characters (16+ characters recommended for high security).
Select Character Sets
Toggle uppercase letters, lowercase letters, numbers, and special symbols (!@#$%^&*) to match your requirements.
Exclude Ambiguity

Frequently Asked Questions
Everything you need to know about processing files securely in your browser
How secure are the passwords generated by this tool?
The passwords are mathematically secure. The generator uses the browser's cryptographically strong Cryptographic Pseudo-Random Number Generator (window.crypto.getRandomValues) rather than standard, predictable random functions.
Are my generated passwords saved on a server?
No. The passwords are created entirely locally in your browser's memory and are never transmitted over the internet or stored anywhere.
What makes a password strong?
Password strength increases with length and complexity. A strong password should be at least 12-16 characters long and include a mix of uppercase and lowercase letters, numbers, and special symbols.
Can I generate passwords excluding specific characters?
Yes, the tool supports options to exclude ambiguous characters (such as 1, l, I, 0, O) which are often confused when read or written.
