This chart summarizes the current generated batch without exposing its password text. A small sample cannot prove random-number quality.

The ceiling assumes the selected generator model is uniform. It is not a guarantee for a reused, human-chosen, or exposed password.

Session-only generation history and export
This panel keeps only batch metadata in session storage. Password text stays in memory and is exported only if you explicitly choose it.
Warning: exported files may contain sensitive passwords. Save them only in a trusted location.

Password crack time estimator
See how common words, patterns, and length affect an estimated attack time.
Evaluated only in this browser. Never uploaded, logged, or saved.
Estimated time · offline fast hash (10 billion guesses/second)
Enter a password to estimate
Pattern dictionary coverage is limited for this language; the estimate still checks common passwords, sequences, and repeats.
Compare four attack scenarios
Online, rate limited (100/hour)
—
Online, no rate limit (10/second)
—
Offline, slow hash (10,000/second)
—
Offline, fast hash (10 billion/second)

Estimate only—not a guarantee. Actual time depends on password storage, hashing cost, attacker hardware, and whether the password is reused or exposed.
About this generator
This tool is configured for random multi-word passphrases. Every result is created on this device with the Web Crypto API and is never sent to PwdGen.
This preset starts with passphrase mode and generates 10 independent results at a time. Every visible setting remains adjustable, and generated values are not sent to PwdGen.
When to use it
Credentials that may need to be typed manually
Password-manager master password candidates
Long secrets where readability matters
How to use the result safely
Prefer four or more unrelated words
Do not use a familiar quotation or personal phrase
Check whether the destination permits spaces or separators
Important limitation: Memorability does not make reuse safe. Short or predictable phrases can still be guessed.
Generation and privacy method
The preset uses the browser Web Crypto API for random selection. Regenerating, changing settings, selecting, and copying results do not send generated credentials to PwdGen. The password crack-time estimator also runs locally and is an estimate, not a guarantee.
Passphrase Generator FAQ
What makes this passphrase generator memorable?
It uses readable or pronounceable structure while keeping the choices random. A familiar quote, name, or personal phrase is not equivalent to a random passphrase.
How many random words should a passphrase contain?
Four or more unrelated words are a practical starting point for many uses. The right choice depends on the word list, selection method, destination policy, and threat model.
Can I reuse a memorable password?
No. Memorability does not make reuse safe. Keep every account credential unique and store it in a trusted password manager.
