Abstract
Disclosed are various examples for facilitating distribution of security codes for a two-factor authentication scheme or one-time passwords. Security codes can represent one-time passwords or shared secrets used to seed one-time password algorithms. The security codes can be sent through restricted communications channel to a client device. Rather than using an insecure communication link such as SMS for communication of security codes, the security codes can be sent through the restricted communications channel to reduce the possibility of leakage of the security codes.
