Out-of-Band Authentication
Geek Speak:
This security method adds an extra layer of verification by using a different communication channel for authentication, such as sending a code to a phone via SMS or push notification. Financial institutions and other organizations often use it to enhance security and prevent unauthorized access.
Plain English:
What Is Out-of-Band Authentication?
Out-of-Band Authentication is an additional layer of security that utilizes a separate method to verify your identity when logging in, typically through a device or channel that’s not connected to the primary login system.
For example, if you log into your email on your computer, the system might send a code to your phone via text message or a mobile app. You then enter that code to verify that you’re the actual user.
This is helpful because even if a hacker steals your password, they’d still need access to your second device to break in.
In simple terms:
It’s like having two locks on a door, and the keys are kept in different places.
