Storing the information helps users to complete single-line text fields. The next time that user visits a Web page and begins typing in a text field with the same name, the autocomplete attribute prompts an AutoComplete box to appear, providing the user with a list of previously used data. An AutoComplete box is the primary interface for presenting data to the user. Until an entry in the AutoComplete box is selected, the data remains on the user's computer and is never accessible to a Web site. User experience is simplified by helping the user fill out forms.
User information remains secure.
While users can see their private information on a Web site, a Web site cannot see the list of personal information until one of the stored values is selected and the field is filled in. AutoComplete is an easy feature to incorporate into Web sites, and it provides a nonintrusive advantage for Web authors and users. The list of suggestions is saved in an encrypted store on the user's computer and is not accessible to Web sites. Because the user interface is integrated with the browser, it is streamlined with the Web page and transparent to the user. Individual Web sites do not need to make any changes to their content to use AutoComplete.
