The disclosed embodiments include computerized methods and systems that facilitate two-factor authentication of a user based on a user-defined image and information identifying portions of the image sequentially selected by the user. In one aspect, a communications device presents a first digital image of a first user on a touchscreen display. The communications device may receive, from the first user, information identifying portions of the first digital image selected in accordance with a candidate authentication sequence established by the first user. The selected first image portions may, for example, be associated with corresponding facial features of the first user. The communications device may determine whether the candidate authentication sequence matches a reference authentication sequence associated with the first digital image, and may authenticate an identity of the first user, when the first selection sequence is determined to match the second selection sequence.
