Password Generator

The Password Generator creates strong, random passwords using the browser cryptographic RNG, so the result is genuinely unpredictable. Set the length and which character classes to include, and generate as many as you need. A good password is long, mixes character types, and is unique to each account, so pair the generator with a password manager and never reuse the output. The tool is local, meaning the passwords it produces are never recorded or transmitted, so you can keep them in a secret you trust. Password strength comes down to length and unpredictability, and human chosen passwords fail on both counts because they follow patterns that attackers enumerate first. A generator sidesteps that by using a cryptographic random source, which produces values with no structure to exploit, no relation to dictionary words, and no reuse from one account to another. Length is the dominant factor, since each additional character multiplies the search space, and mixing character classes raises the space further while making the value harder to guess. The two rules that matter operationally are to generate a different password for every account and to store them in a password manager rather than in memory, because reuse is what turns a single breach into a cascade of compromised accounts. Uniqueness also limits the damage of a leak to one service instead of many. A local generator has the additional property that the values it produces are never recorded or transmitted, which means the password exists only where you put it, and that is the whole reason to generate rather than accept a suggestion from somewhere else.
