What makes a strong password?

A strong password is long before it is complex: length adds far more resistance to guessing than symbol substitutions do. Aim for at least 16 characters, unique to each account, generated randomly rather than chosen. Passwords generated here are produced in your browser and never transmitted.

Runs in your browser. Your files and text never leave your device - nothing is uploaded.

Why use Password Generator?

A strong password is mostly a matter of length and randomness - not clever substitutions like swapping "e" for "3", which pattern-based cracking tools already account for. Truly random passwords, generated without any human-predictable pattern, are dramatically harder to guess or brute-force than anything a person would consciously choose. This generator draws every character from the browser's cryptographic random number generator, the same source used for encryption keys, with configurable length from 6 to 64 characters and any mix of lowercase, uppercase, digits and symbols. The result never leaves your device - it's created, shown, and copied locally, with nothing transmitted or logged anywhere. The strength meter grades what you generate by length and character variety, and you can produce several passwords at once when setting up more than one account. The useful mental model is entropy, measured in bits: each extra character multiplies the number of possibilities by the size of the character set, so length compounds where complexity only adds. A 16-character password using all four sets carries roughly 105 bits, which no current hardware can brute-force; a 12-character one still carries about 79 bits, which is more than enough for anything protected by a properly hashed login. What entropy cannot protect against is reuse: a perfectly random password leaked from one site opens every other site it was used on, which is why one generated password per account, kept in a password manager, matters more than any single password's length.
