Strong Password Generator
Generate strong, truly random passwords that no attacker can guess or brute-force. “Password123” and your pet's name are the first things cracking software tries — and reused passwords mean one leak compromises every account. This generator uses the browser's cryptographically secure random engine (the same quality used for encryption keys) to produce passwords of any length, mixing uppercase, lowercase, numbers and symbols to your rules. A live entropy meter shows the real strength of every password, and one click copies it to your clipboard. Nothing is transmitted or logged — every password is generated on your device and exists nowhere else.

Why use this password generator tool?
Cryptographically secure
Uses the Web Crypto API — true cryptographic randomness, not the predictable Math.random() used by lesser generators.
Live entropy analysis
See the password's real strength in bits of entropy, with crack-time estimates for offline brute-force attacks.
Full control over rules
Length from 6 to 64 characters, toggles for each character class, and an option to avoid look-alike characters like 0/O and 1/l.
Zero transmission
Passwords are generated and displayed locally only — never sent to a server, never logged, never stored.
