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.
