8. A system comprising: a processor; and a memory coupled with and readable by the processor and storing a set of instructions which, when executed by the processor, cause the processor to control presentation of sensitive information in a user interface of an application by: generating the user interface of the application, the user interface comprising a text field for displaying a field of information identified as sensitive, wherein the field of information is associated with a sensitivity level specifically defined for the field of information, wherein different sensitivity level including high-sensitive level or low-sensitive level is defined according to different data content of the field of information, and wherein the text field initially displays the field of information identified as sensitive in a masked form; presenting the generated user interface to a user of the application; receiving an unmasking request from the user to unmask the field of information identified as sensitive; determining whether the unmasking request is a first unmasking request from the user in a session or a subsequent unmasking request from the user in the session; determining to grant the user access to the field of information identified as sensitive based on: whether the unmasking request is the first unmasking request or the subsequent unmasking request; a saved password for the user; and the sensitivity level specifically defined for the field of information; determining, from a plurality of methods of unmasking, a method of unmasking the field of information identified as sensitive, wherein the determining is based on the sensitivity level specifically defined for the field of information, and wherein the plurality of methods of unmasking comprises: displaying, separate from the text field, a tooltip with the field of information in an unmasked form when the sensitivity level specifically defined for the field of information is high-sensitive; and replacing, within the text field, the field of information identified as sensitive in the masked form with the field of information in the unmasked form when the sensitivity level specifically defined for the field of information is low-sensitive; updating, based on the determined method of unmasking, the user interface to display the field of information in the unmasked form.
8. A system comprising: a processor; and a memory coupled with and readable by the processor and storing a set of instructions which, when executed by the processor, cause the processor to control presentation of sensitive information in a user interface of an application by: generating the user interface of the application, the user interface comprising a text field for displaying a field of information identified as sensitive, wherein the field of information is associated with a sensitivity level specifically defined for the field of information, wherein different sensitivity level including high-sensitive level or low-sensitive level is defined according to different data content of the field of information, and wherein the text field initially displays the field of information identified as sensitive in a masked form; presenting the generated user interface to a user of the application; receiving an unmasking request from the user to unmask the field of information identified as sensitive; determining whether the unmasking request is a first unmasking request from the user in a session or a subsequent unmasking request from the user in the session; determining to grant the user access to the field of information identified as sensitive based on: whether the unmasking request is the first unmasking request or the subsequent unmasking request; a saved password for the user; and the sensitivity level specifically defined for the field of information; determining, from a plurality of methods of unmasking, a method of unmasking the field of information identified as sensitive, wherein the determining is based on the sensitivity level specifically defined for the field of information, and wherein the plurality of methods of unmasking comprises: displaying, separate from the text field, a tooltip with the field of information in an unmasked form when the sensitivity level specifically defined for the field of information is high-sensitive; and replacing, within the text field, the field of information identified as sensitive in the masked form with the field of information in the unmasked form when the sensitivity level specifically defined for the field of information is low-sensitive; updating, based on the determined method of unmasking, the user interface to display the field of information in the unmasked form. 12. The system of claim 8 , wherein the determined method of unmasking includes displaying the tooltip with the field of information identified as sensitive in the unmasked form, wherein the instructions, when executed by the processor, further cause the processor to perform: updating the user interface to display the tooltip with the field of information identified as sensitive in the unmasked form; and upon receiving an indication of a mouse click from the user, re-masking the field of information by removing the tooltip from the user interface.
