About this tool
The Password Generator creates strong random passwords using your browser's cryptographically secure random number generator — the same API used by password managers. Choose the length and which character sets to include, and a strength meter rates the result.
Length matters more than complexity: a 16-character password with three character sets is dramatically harder to crack than an 8-character one with four. Use a unique password per site and store them in a password manager rather than reusing one.

Attackers try word lists first. Random character strings have no patterns to exploit, forcing a full brute-force search.
