Is there any way to password protect a Visio 2010 drawing so that unauthorized users cannot make changes?

Hello,

As far as I know, Visio does not have any feature like Word's "Protect Document" which forces a prompt for a password. There is a very limited protection feature, please see this topic for Visio 2010 describes the functionality:

BTW, this request may be done via some VBA code.

Hope it's helpful.

What about making the file read only to all users except for a select few?

Thanks for your input.

Hi,

Since your situation now, we may try to use following workarounds.

1) If your company is using SharePoint, you might be more easily able to put it in a storman-norman-editable-only library somehow

2) Embed the Visio file into a Word document as an object, then protect the Word document.

Hope it's helpful.
