Passphrase entropy ≈ words × log₂(wordlist size).

Quantity

Generate up to 20 at once.

Strength: — —

What affects strength?

Strength (bits of entropy) increases with longer length and larger character pools. Aim for 80+ bits for important accounts.

How it works

This tool builds a character pool from your selected options, guarantees at least one character from each chosen set, then shuffles the result using the Fisher–Yates algorithm. Entropy is estimated as length × log₂(poolSize) (or words × log₂(wordList) for passphrases).

FAQs

Is this tool free and private?

Yes. Everything runs locally in your browser — no uploads, no tracking beyond standard site analytics.

Will you save my passwords?

No. We never store any generated passwords. Optionally, we persist your settings in your browser to speed up repeated use.
