Answer: This form of identification is known as "MULTIFACTOR/TWO-FACTOR" authentication.
Explanation: Multifactor/Two-Factor authentication is a process of verifying two or more security pathways before access can be granted. It helps an owner to build a strong security pathways, as it enables more than one security options to a device. Example is using a security code and finger print to unlock our phone.
Because a passphrase must be entered and a retinal scan must be accepted before one can access the database, that means it has two security pathways. This makes it a Multifactor/Two-Factor authentication.
