An example method includes determining a subset of content displayed by an application on a user interface (UI) of a user device, wherein the subset excludes user-specific information. The method further includes transmitting a request to a remote provider for at least one template for use with the application, wherein the request comprises the subset of content displayed on the UI. The method also includes receiving a response to the request from the remote provider, wherein the response comprises the at least one template indicating how to process user input data in one or more text input fields displayed by the application on the UI, and generating a prompt to authorize transmission of the one or more user input values to the remote provider for future use in autofill, wherein the prompt is customized by processing the one or more user input values using the at least one template.
