Password Builder

Build passwords a hacker can't crack and you can still remember. 8 quick rounds, 3 lives.

Never type your real password into a game, a quiz or a form that asks for it. Here you only build made-up ones from tiles.

Password Builder

Build made-up passwords from tiles: random words, numbers, symbols, and a few traps like leaked passwords, keyboard patterns and personal facts. A crack-time meter shows how long an example attacker making 10 billion guesses a second needs on average. Hit each round's target while keeping enough memory stars, in 8 quick rounds.

How to play

Build. Tap tiles to add them, tap them again to remove. Tweaks add a capital, look-alikes like @ for a, or a ! at the end.
Beat the meter. Reach the round's crack time, from 1 day to 1 million years, against an example attack of 10 billion guesses a second.
Stay memorable. A word is one easy chunk to remember; random characters cost one each. Keep the stars the round asks for.
Score. 100 per passed round, +25 per memory star and up to +50 for speed. A failed round costs one of 3 lives.

Quick tips

Length wins. Each random word multiplies the guesses by 7,776. A capital or a ! only doubles them.
Skip the traps. Leaked passwords, keyboard walks like qwerty and facts on your profile are the first things crackers try.
Random means picked by chance. Words you choose because they mean something are easier to guess. Let a dice roll or a generator pick them.
Words beat symbol soup. Random characters are strong but each one is a separate thing to remember. A few random words stick better.
Meet site rules cheaply. If a site needs a digit or a symbol, add one, but the strength still comes from length.
