Passwords are the last thing
people think about.
Until they get hacked.

01

Generators with no taste

Most password tools spit out a random blob with no context. They give you a string but never tell you why it's strong — or that it isn't.

02

No feedback, no learning

A meter that goes green isn't feedback. PassLab shows entropy in bits, time to crack, and exactly which choices moved the needle.

03

Unmemorable, so reused

If you can't remember it, you reuse it. We support passphrases, word-to-password transforms, and clean exports — so good passwords actually stick.

Six tools.
One quiet tab.

Each feature does one thing well, runs locally, and explains itself. No upsell, no account walls.

/01
Time-to-crack visualiser
3 million years

For a 20-char mixed password at 10B guesses/sec — see the math, not a vibe.

Passphrase mode
4 words, uncrackable

Diceware-style word lists. Easy to remember, impossible to brute-force.

/03
