These attacks occur when an unauthorized third party intercepts the communication between a user and an online service, gaining access to sensitive information such as login credentials. By employing a separate channel for authentication, even if the primary channel is compromised, the attacker would still need to gain control over the secondary channel to successfully breach the system. Out-of-Band Authentication also provides protection against various other types of attacks, including phishing, keylogging, and credential stuffing.
Phishing attempts, where attackers trick users into revealing their login credentials through fraudulent websites or emails, can be thwarted with out-of-band authentication. By sending an authentication request to a separate channel, users can verify the legitimacy of the login attempt before providing sensitive information. Furthermore, Out-of-Band Authentication proves beneficial in situations where multi-factor authentication (MFA) is required. MFA combines two or more independent authentication factors, typically something the user knows (such as a password) and something the user possesses (such as a mobile device).
