Integrating additional data sources into a mobile autofill mechanism

A user device comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media that stores program code, wherein the program code, when executed by the one or more processors, causes the one or more processors to:
• request, from a first provider and from a second provider, candidate data for use in autofill for an application displayed on the user device, wherein requesting the candidate data comprises transmitting a subset of content displayed on the user device to each of the first provider and the second provider;
• receive, from the first provider, a first data set comprising one or more candidate values corresponding to a first set of one or more input fields of the application;
• receive, from the second provider, a second data set comprising one or more candidate values corresponding to a second set of one or more input fields of the application;
• detect that an input field of the application has focus, wherein the input field is included in the first set and the second set;
• responsive to detecting that the input field of the application has focus, cause a selectable list to be displayed on the user device, wherein the selectable list includes a first selectable option corresponding to the first data set from the first provider and a second selectable option corresponding to the second data set from the second provider;
• receive user input data indicating a selected data set from the selectable list;
• and
• responsive to receiving the user input data, fill one or more candidate values from the selected data set into one or more corresponding input fields of the application.

A non-transitory computer readable medium having stored therein instructions executable by one or more processors to cause a user device to perform functions comprising:

• requesting, from a first provider and from a second provider, candidate data for use in autofill for an application displayed on the user device, wherein requesting the candidate data comprises transmitting a subset of content displayed on the user device to each of the first provider and the second provider;
• receiving, from the first provider, a first data set comprising one or more candidate values corresponding to a first set of one or more input fields of the application;
• receiving, from the second provider, a second data set comprising one or more candidate values corresponding to a second set of one or more input fields of the application;
• detecting that an input field of the application has focus, wherein the input field is included in the first set and the second set;
• responsive to detecting that the input field of the application has focus, causing a selectable list to be displayed on the user device, wherein the selectable list includes a first selectable option corresponding to the first data set from the first provider and a second selectable option corresponding to the second data set from the second provider;
• receiving user input data indicating a selected data set from the selectable list;
• and
• responsive to receiving the user input data, filling one or more candidate values from the selected data set into one or more corresponding input fields of the application.
