Tool
How long would guessing your passcode take?
Choose your lock, and the tool counts it against the waits Sealed adds after wrong tries: the number of possible codes, the time to try them all, the time to reach halfway, and the most tries a person gets in a day, a week or a month. For the default six digits, trying them all takes about 114 years. Then type a code shaped like yours to see whether it has an easy shape that a person would try first.

Nothing you choose or type leaves this page. The tool pages are served with a content security policy that forbids every network connection, so the page’s own script could not send a photo anywhere, not even back to this site. A check on every build fails if a tool script uses cookies, local storage, session storage or IndexedDB, so the photo tools keep nothing in your browser.
- Possible codes
- 1,000,000
- Time to try every one
- about 114 years
- Time to reach the halfway point
- about 57 years
- Most guesses a person can make
- 7 in the first hour, 30 in the first day, 174 in the first week and 726 in the first 30 days.
Counted for someone who types every guess the moment the last wait ends, never guesses right, and with the limit left at three wrong tries. A wait refuses the right code too, so there is no way to slip one in early.
Does your code have a common shape?
Type a code shaped like yours. You do not need to type your real one. Nothing you type is kept.
Reading the four answers
- Possible codes. Ten digits in each place, or every ordered choice of four or more of the nine dots on the smallest pattern pad. Nothing about Sealed goes into this line.
- Time to try every one. The worst case for the guesser: your code is the last one left.
- Time to reach the halfway point. The typical case. A guesser with no clue about your code is as likely to find it in the first half as in the second.
- Most guesses a person can make. The ceiling the waits put on a day, a week and a month, whatever the lock.
Sealed’s default passcode is 6 digits, and you can choose 4 or 9 digits or a password instead. This tool covers the digit lengths and the pattern, not a password. It counts a guesser who types each code the second a wait ends and never gets lucky. Unless you change the limit, the first wait starts at the third wrong try in a row. The waits then grow from 30 seconds to 60 minutes, and the passcode guessing guide lists every step.
The checked figures
These are the figures the tool must match. Each was counted by running Sealed’s own wait code.
| Lock | Time to try every code |
|---|---|
| Four digits | about 14 months |
| Six digits, the default | about 114 years |
| Pattern, at most 985,824 codes | at most about 112 years |
Most tries in the first hour: 7. In the first month: 726.
The pattern row is the smallest pad. A Sealed pattern is drawn on a grid of 3 by 3 up to 6 by 6 dots and has to connect at least 4 of them, and a drawing that is too short is told so and isn’t counted as a wrong try. A bigger pad has far more patterns, so its time to try every one is longer.
Why the shape check is there
Every time above treats each code as equally likely. A person guessing does not. They start with what a thumb finds quickly and a memory keeps easily: the same key pressed six times, a walk along the pad, two keys taken turns with, a year, a day and month. A code of that kind can fall on the first afternoon, before the long waits begin.
The check reads the digits you type and names any of those shapes it finds. It cannot know that a code is your street number or your car’s plate, so a clean result is a good sign and nothing more. When you pick a new code, let dice or a random generator choose the digits, and change nothing afterwards.
Where Sealed helps, and where it doesn’t
It helps by making every wrong try cost time. During a wait Sealed refuses every way in, the right passcode and Face ID included, and doesn’t count those tries as wrong. Closing the app and opening it again does not reset anything. Sealed keeps the wrong-try count and the wait when you close it and open it again, and the count clears only after a correct unlock or a passcode reset with your recovery key.
It doesn’t slow down someone who already knows your code, from watching you type it or from a code you use elsewhere. The tool counts guesses, not a code that was seen. The lock comparison guide covers Dual Lock, which asks for a face on top of the code. Dual Lock asks for your passcode and a Face ID match together, and it is part of Sealed Pro.
Questions and answers
Why is the nine-digit time not in the table on this page?
The table holds only numbers counted from the app’s own code and checked. The tool works out nine digits by the same rule while you use it: they have a thousand times as many codes as six, and once the waits reach their longest step every guess costs the same.
Do the waits apply to Face ID too?
A Face ID or Touch ID attempt that doesn’t match counts as a wrong try, but cancelling the prompt, or iOS cancelling it, does not. During a wait Sealed refuses every way in, the right passcode and Face ID included, and doesn’t count those tries as wrong.
Is it safe to type my code into the shape check?
You do not need your real code: type one with the same shape. The tool pages are served with a content security policy that forbids every network connection, so the page’s own script could not send a photo anywhere, not even back to this site. A check on every build fails if a tool script uses cookies, local storage, session storage or IndexedDB, so the photo tools keep nothing in your browser.
