Exemplary methods, apparatuses, and systems include a first server transmitting, to a first client device, a scannable code for display on the first client device. The scannable code encodes a session identifier for a session between the first client device and the first server. The first server receives a transaction identifier to authenticate a transaction within the session between the first client device and the first server. The transaction identifier is transmitted to the first server in response to a second client device scanning and decoding the scannable code displayed on the first client device to obtain the session identifier. The first server transmits an indication of a successful authentication to the first client device in response to the received transaction identifier. |
