Security experts have long established two-factor authentication as one of the best ways to keep your accounts secure—and a physical key can be part of that.
Instead of entering a password and a code sent to a mobile device, you log in by plugging in the physical key to gain account access. If hackers were to get ahold of user passwords, they wouldn’t be able to do anything with them without the key.
Yubico, one manufacturer of physical security keys, previously only made them compatible with Android devices. The company previewed a new Yubikey for iPhones and iPads this week at Consumer Electronics Show in Las Vegas.
If you’re still not sold on the concept, multiple web browsers support the use of physical security keys, including Safari, Firefox, Chrome and Microsoft Edge.
Additionally, Google requires every employee use a physical security key. The company says this practice curbs instances of phishing.
