Password encryption of an Office file

You can use a password to encrypt Office files. The example in these instructions concerns a Word file, but the same principle applies to other Office files as well. Use a strong password that you can remember. IT support cannot restore the password for you.

See Microsoft’s instructions for more information about file encryption.

  • Windows: Open  File  >  Info  > Protect Document > Encrypt with Password.
    Mac: Tools > Protect Document 
  • Enter the password twice.
  • More information is available on Microsoft’s instructions page.
