Pattern strength
Draw your pattern. See how long it holds.
Your browser counts the patterns of the same length, flags the shapes guessers try first, and times a full search at Vaulteo's speed.
Draw 4 dots or more. Draw again to test another.
Draw the pattern you'd use, or one like it. This page counts the patterns of the same length, checks the shapes guessers try first, and times a full search.
Make a pattern that lasts
- Use 7 dots or more.
- Start away from the corners.
- Cross your own line at least once.
- Jump over a dot now and then, so the shape stays hard to read.
Vaulteo turns your pattern into a key with 600,000 rounds of PBKDF2-SHA512, so each guess costs about half a second. Read how the pattern lock works.
Does this page save my pattern?
No. Your browser does the math, and the page forgets the pattern when you draw another or close the tab.
How many patterns fit on a 5 × 5 grid?
Billions once you use 7 dots or more. Every extra dot multiplies the count by about 20.
Why does a corner start lower my score?
Studies of Android unlock patterns found that most people start in a corner, the top-left one most often. Guessers try those first.
