How to Set Up a Quicken 2010 File Password
You can set up a password for a Quicken file (although that password protects only that file — not your version of Quicken or your computer, as a whole).
1If the file you want to password-protect is not the active file, choose File→Open, and then double-click the file you want.
That file becomes active in Quicken
2Choose File→Set Passwords for This Data File on the menu bar.
Quicken displays the Passwords submenu, which lists two commands: File and Transaction.
4Enter the password into the New Password text box.
You can use up to 16 characters. Quicken differentiates between lowercase and uppercase characters, by the way, so Washington, wASHINGTON, and WASHINGTON are all different, from its point of view. Quicken doesn’t display the actual characters you type; it displays asterisks. If you type Dog, for example, it displays ***.
5Enter the password you want to use again, this time in the Confirm Password text box, and then click OK.
Congratulations! You’re done.
