Answer:
Push notifications.
Step-by-step explanation:
In Computer technology, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Multi-factor authentication is a security system process that requires a user to verify his or her identity by providing two categories of credentials. First of all, the user is required to provide his or her login credentials (username and password) and lastly, a unique PIN known as One Time Password (OTP) that was sent sequel to logging in.
In this scenario, a company is implementing multi-factor authentication (MFA) for all applications that store sensitive data. The information technology (IT) manager wants MFA to be non-disruptive and user friendly.
Hence, the technology the IT manager should use when implementing MFA is push notifications.
Push notifications refers to an internet-based communication system used for generating or creating messages that are sent automatically to the mobile phone of an end user even when the particular application is not in use or open. Push notifications are user-friendly because they can either be approved or denied by a user.
