Why Trezor ask for my password every 5 minutes?
When I am doing a transaction after 5 minutes take me out asking for my 6 digital #s after that I start doing the transaction again fast before take me out again, this happen after I installed the update from Trezor.

how can I change or turn it off that?

@pvattrezor yes, device locks after certain time for security, you can set this time in the settings
