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.
