Hi there, 

Welcome to Box Community and glad to help!

To ensure that we're on the same page, can you tell us more regarding the pattern you've forgotten? Is this used to log in to your Box account? 

We'd love to further assist! 

Around 3 months back I have change my phone and not been using box when I istall the application to a new phone still it ask for the pattern but i forget so i change my password through email but pattern still there.
