Abstract: A system and method for performing autofill of fields in a web page are disclosed. The method may include: obtaining user data associated with a user device used to access one or more web pages from a web server; obtaining site data from data communication messages between the user device and the web server; determining, using a page classifier module, if a current web page from the one or more web pages includes at least one input field for autofill; when the current web page is determined to include at least one input field for autofill: using a field classifier module to identify one or more input fields for autofill from the at least one input field; generating, based on one or both of the user data and site data, one or more values for the one or more input fields; and performing an autofill of the one or more input fields with the one or more values.
