Setting a Password FLIGHTCHECK® allows you to set your own password in order to prevent others from running your FLIGHTCHECK®, effectively stopping them from changing your particular setup or preferences settings. Having a password can also serve as a security measure that will prevent others from viewing the contents of certain documents. You can set a password by selecting “Set Password...” from the Edit menu: Enter your password (up to 8 characters) and click on the Set Password button. You will be asked to retype your password in order to verify it. To change an existing password, you will first need to enter the correct password before clicking the Set Password button.
