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).
If 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
Choose File→Set Passwords for This Data File on the menu bar.
Quicken displays the Passwords submenu, which lists two commands: File and Transaction.
Quicken displays the Quicken File Password dialog box.
Enter 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 ***.
Enter the password you want to use again, this time in the Confirm Password text box, and then click OK.
Congratulations! You’re done.
Assigning a password to a file doesn’t prevent you from doing anything with the file that you would normally do. However, the next time you try to use this file — after you start Quicken or when you try to select the file by choosing File→Open — Quicken will ask you for the file’s password. You need to supply the password to gain access to the file.
