Add support for password protected documents
Add support for creating and opening encrypted password protected documents like in the desktop version of Word
For Excel this suggestion is under review (https://excel.uservoice.com/forums/274580-excel-online/suggestions/12346476-add-support-for-password-protected-workbooks) It makes sense to have this feature implement for online Word and Excel.
The need for managing password protection (turning on or off) protection on the web is very important and needed!!
