Yes... using these plugins:
   http://www.TiddlyTools.com/#TiddlerPasswordPlugin
   http://www.TiddlyTools.com/#TiddlerPasswordPluginConfig
   http://www.TiddlyTools.com/#TaggedTemplateTweak

1) install the above plugins
2) create a tiddler called [[LockedEditTemplate]], containing:
----------------------
<span macro="getTiddlerPassword">
[[EditTemplate]]
----------------------
3) Edit the TiddlerPasswordPluginConfig (change default "admin" password to 
some other password)
4) Tag desired tiddlers with "locked"

When you try to edit a 'locked' tiddler, the alternative LockedEditTemplate 
is used, which invokes the <<getTiddlerPassword>> macro *before* rendering 
the editor controls.  If the incorrect password is entered, you are 
prompted to try again, until either the correct password is input or you 
cancel the password prompt dialog.  If you cancel the password dialog, the 
tiddler you were trying to edit is automatically closed, thus preventing 
you from editing it.  If you enter the correct password, the tiddler editor 
is displayed and you can proceed to edit the content as usual.

enjoy,
