For those who are unfamiliar, Out-of-band (OOB) authentication helps end-users to prevent fraud. It works using a secured communication channel.
Enterprises are adopting OOB technology for high-risk transactions to verify the identity of the user and authenticate for both financial and non-financial transactions.
OOB authentication makes use of two different networks working together to identify a user. OOB authentication technology is a kind of multi-factor authentication.
This technology works well in a situation when any hacker gains security credentials to the account of a user. It will not surpass without access to the second authentication network.
The Out-of-band (OOB) authentication method is cheaper to deploy compared with keys and other complex biometric technologies.
Hardware Out-of-band (OOB) authentication tokens and mobile phone-based OOB authentication tokens, such as SMS and back-up calls, are the available OOB authentication methods.
