OOB stands for Out-Of-Band. Out-of-band authentication is a type of two-factor authentication that requires a secondary verification method through a separate communication channel along with the typical ID and password. Out-of-band authentication is often used in financial institutions and other organizations with high security requirements.

To further clarify,  OOB (Out-Of-Band) authentication, is the process in which the user retrieves an authentication credential (like a One Time Password [OTP]) from some other electronic channel than the one that the user requested it on.  Electronic channels can be anything on a computer, like a web site, or Windows login, or VPN access.  The term OOB is typically used to refer to when an Email or SMS text is sent to the user and the message contains a One Time Password, which the user then types into the original electronic channel to authenticate themselves.  There are many other solutions that fit into this definition of OOB authentication, including the OneSpan Cronto color cryptogram.  Many of these are much more secure than Email or SMS virtual OTP.  It is important to point out that OOB authentication by itself is not two-factor authentication.  In some cases, OOB authentication can be accepted as one of the second forms of authentication that make up a two-factor authentication solution.  If you are interested to learn more about OOB authentication, please let us know.
