Abstract: Systems and methods for cryptographic authentication are provided. A transport service may establish a connection with a login device, where a user is attempting to log in via a web browser. The login device may display a graphical code that encodes a unique URL provided by the transport service. A user may use an authenticator device to image the graphical code. A browser within the authenticator device may be opened and access the URL. The transport service may utilize the authenticator device to perform a proximity-based authentication.

Abstract: Provided is a network-enabled method for creating an online account using a network of devices. The method comprises: receiving by an authentication system, a request to create an online account with an online server; generating a visual graphical code by the authentication system, which is displayed on a display screen and comprises a validation identity; acquiring image data of the visual graphical code from a user device with aid of optical detection apparatus, by capturing an image of the visual graphical code displayed on the display screen; processing the image data to extract the validation identity; based on the validation identity identifying an online serve provider associated with the online server and user information categories associated with the online account; and based on identification information related to the user identifying the user, and the data to the online server for the online account with the online server.

Abstract: Provided herein are systems and methods for verifying online communications. A sender and/or a recipient of an online communication can be a registered user of a verification system. Upon request by the sender and/or the recipient in relation to a particular instance of an online communication, the verification system can (1) confirm that the sender and/or the recipient is a registered user of the verification system, (2) verify that the sender and/or the recipient has sent and/or received, respectively, the particular instance of the online communication, and (3) communicate the verification of the particular instance of online communication to the sender and/or the recipient.

Abstract: Provided herein are systems and methods for verifying emails. Upon request by a sender in relation to a sender's email, a verification system can generate a visual graphical code corresponding to an email identity of the sender's email, acquire image data of the visual graphical code from a recipient device with aid of optical detection apparatus, and process the image data to extract the email identity of the sender's email so that the recipient can verify whether the sender in fact sent the email.
