You are required to keep your e-Portfolio password-protected or private, and to respect the privacy of students, institutions, and employers by making sure that their names are not identifiable in your e-Portfolio.
Following the Permissions directions for the D2L e-Portfolio protects the privacy of any content in that publication. Only the author and any person the author may send the e-Portfolio URL to will have access to the content.
E-Portfolios that are built as external web sites or on wikis or on any platform other than a properly permitted SLIS D2L e-Portfolio are web searchable UNLESS they are password-protected.
To summarize: as long as the e-Portfolio is in D2L and the proper permissions are on, the contents remain private and not web-searchable. IF the e-Portfolio is NOT in D2L and properly protected, then it needs to be password-protected.
A password-protected e-Portfolio or a "private" D2L e-Portfolio can be viewed by those individuals you choose to allow to view. So if you choose, for example, to make the contents of your e-Portfolio available to certain individuals in your job search, you can do so.
