Password Generator

Weak passwords remain one of the most common causes of security breaches. Attackers use automated tools capable of testing billions of password combinations per second. A short or predictable password can be cracked in seconds, giving attackers access to your email, financial accounts, and personal data.

A truly secure password must be generated randomly, not chosen by a human. People tend to use predictable patterns — dictionary words, birthdays, pet names, or simple character substitutions like “p@ssw0rd” — all of which are trivial for modern cracking tools to defeat. Random generation eliminates these patterns entirely.

This tool uses the Web Crypto API (crypto.getRandomValues()) to generate passwords with true cryptographic randomness. The entire process runs in your browser. No passwords are ever transmitted to a server, logged, or stored anywhere.

Password strength is measured in entropy — the number of bits of randomness in a password. Each bit doubles the number of possible combinations. A password with 80 bits of entropy has over a septillion (10²⁴) possible combinations, making brute-force attacks computationally infeasible with current technology. We recommend targeting at least 80 bits for standard accounts and 100+ bits for critical accounts.

Even the strongest password cannot protect you if it is intercepted during transmission. When you log into websites on public Wi-Fi or unsecured networks, your credentials may be vulnerable to interception. Combining strong passwords with a VPN like SwissGuard ensures your login data is encrypted end-to-end, keeping your accounts safe from both brute-force attacks and network-level surveillance.
