Chrome: We all have plenty of reasons to password-protect bookmarks. Maybe you don't want others to see what you are checking out on a daily basis, or you are secretly shopping for a gift. Secure Bookmarks password-protects your bookmarks to keep them away from snoopers.
When you want to bookmark a page, hit the button, and it's instantly added to the list. You can then edit the link by clicking the pen icon and changing the title. It's all controlled under one password, and if you combine it with Incognito Mode, you can password-protect and hide any links you want to keep private.
