Frequently Asked Questions
Are the generated passwords secure?
Yes. The tool uses the browser's crypto.getRandomValues secure random source, and passwords are generated locally β nothing is uploaded or stored.
Why is at least 12 characters recommended?
Length is the first factor in password strength. A 12-character mixed password is far harder to brute-force than 8 characters, and major security bodies recommend 12+.
Is selecting every character type the most secure?
The more types and the longer the length, the more secure β but prioritize meeting the target platform's rules. The strength indicator evaluates holistically.
Are passwords saved on a server?
No. Generation happens entirely in your browser, with no data uploaded or recorded.
