Password-protecting a file
If you have a non-shared database file on your computer and you want to prevent others from opening it, you can password-protect the file.
After password-protecting a file, you will be prompted to enter an account name and password every time you open the file. Anyone who does not know this account information will not be able to open the file.
To password-protect a database file:
Edit the Admin account so that it has a different account name, a password, and uses the Full Access privilege set. (If the file does not contain an Admin account, create a new account with a password and assign the Full Access privilege set to it.)
See Editing existing accounts and Duplicating and deleting accounts.
For instructions on how to edit the Full Access privilege set, see Editing extended privileges for a privilege set. If you don’t need any extended privileges, leave them disabled.
Warning  Don’t forget the account name and password that is assigned to the Full Access privilege set. If necessary, write it down and store it in a secure place. If you lose or forget this account name and password, you may not be able to access or change the file.
Note  To remove password protection from a file, remove passwords from all accounts. Then, in the File Options dialog box, make sure Log in using is selected, with Account Name and Password set to Admin and a blank password. See Setting file options.
