There's a couple ways this might be accomplished. Give this a try:
Set up a new cell somewhere where your user can enter a password into. I'll
just use B1 for an example. Then, set up your possible data values in a
list. For example, in cells A1:A3. Use the following values.
A1 A
A2 B
A3 =IF(B1="Password","C","")
Set your Data Validation to accept a "List" and choose cells A1:A3 to
populate that list. Note that the List of valid entries will only include
"A" or "B" unless the user has typed in the correct password into cell B1.
Then, "C" becomes a valid entry. Just make sure that the password field is
cleared whenever the users are done entering data (this could also be
accomplished automatically with a VBA BeforeSave event).
You'll also want to set cell A3 up with a "Hidden Formula"
(Properties-->Protection-->Hidden) so that users won't be able to find out
the password by simply selecting that cell. Or, place your data list on a
separate worksheet, then hide that sheet.
