The smartphone has become a vital device for many users, and the iPhone is one of the most common models today. As a result, a lot of important data and accounts are accessible through the use of an iPhone, meaning that security has become far more important for these devices. Multifactor authentication, which is a process of using more than one verification system, has been crucial in increasing cybersecurity. As documented by Forbes, Apple has introduced new ways to improve that security further.
Physical Security Returns
The iPhone is now adding an additional layer of multifactor authentication security in the form of “security keys.” Unlike passkeys, which are entirely digital in form, a security key is a physical object, such as a token that uses NFC technology or a USB device that plugs directly into the phone.
The security key operates by being paired and recognized by only a single device. When attempting to access an iPhone with security key features enabled, in addition to multifactor authentication measures such as face or fingerprint recognition, the security key must either be in proximity to the iPhone or plugged directly into it, depending on the nature of the key. The iPhone will only unlock if the presence and validity of the security key are confirmed.
Why This Matters
Today’s smartphones, including the iPhone, often contain some of the most important data and access in a person’s life. In addition to personal materials such as photos and messages, accounts for everything from banking to shopping are typically part and parcel of accessing an iPhone. In other words, people who have phones stolen and accessed aren’t just losing a convenient form of communication; they may also be granting thieves access to their financial data, work data, and personal data.
This is why multifactor authentication is crucial for device security, especially for devices like iPhones that are small and can be easily lost or stolen. If a phone is lost, the security key requirement prevents others from accidentally accessing the device. In the event of theft, criminals cannot use the data on the phone for broader criminal activities, such as identity theft, emptying bank accounts, and using credit cards to make purchases.
iPhones are incredibly convenient devices, especially with more and more interactions centralized online. However, that same convenience also means the devices are particularly vulnerable and can cause enormous damage if unauthorized users access them.
