Though they're near typically plugged into a computer'south USB-A or USB-C port, some security keys feature wireless Bluetooth or NFC capabilities to connect to mobile devices too. A couple have Lightning plugs to connect to iPhones and older iPads.
How USB security keys fit into ii-factor authentication
Though a USB security key may sound redundant on paper, information technology brings major benefits. Here are some things to consider.
Passwords are easier to figure out than you'd think. Not just practise many people use weak or like passwords for every account, but advanced algorithms and powerful computers can effigy out many "potent" passwords with enough fourth dimension and try.
Furthermore, if you reuse the passwords and usernames on multiple sites, you multiply the risk that those login credentials will be exposed in a data breach. It doesn't matter how strong your countersign is if hackers can use "credential stuffing" to find other accounts where yous utilize it. One data breach could result in many accounts beingness hijacked, even months or years later.
Aside from never reusing passwords, the best way to protect an online account is to use 2FA. When you log into a website from a new figurer or mobile device, the login page will ask you to enter a second hugger-mugger "factor" along with your countersign.
This factor is often a one-time passcode (OTP) sent to your phone via text message, electronic mail, "push" notification or voice call. Authenticator apps can also generate one-fourth dimension passcodes for each account. The thought is that a hacker who has your password won't take your smartphone and thus tin can't receive or generate the right one-time passcode.
Enter the passcode into the login page, and y'all're in. Yous tin ask the site to "recognize" your new device and so that y'all won't need to get through the 2FA process next time yous log into the account.
Why practise I need a hardware security key?
Even so phone-based 2FA isn't foolproof. Hackers can intercept texted codes by "porting" your phone number to another device or having your e-mail messages secretly forwarded. Authenticator-app OTP codes can be "phished" past tricking the user into entering them into phony websites.
Hardware security keys provide the toughest 2FA factor available. They don't depend on any devices likewise themselves. They are an exclusive access point; no one can access your data unless they have both your password and your concrete security central.
A USB security fundamental is an intelligent trivial device that recognizes websites, and because of this, it will end you from entering information on a phishing site out to steal your passwords.
How would I use a USB security key?
Setting up a hardware security key is easy: Log into your website of pick and brand sure 2FA is enabled and set up up. It's OK if y'all've already ready up 2FA to piece of work with texted codes or an authenticator app.

From here on, you lot can utilise the USB security central equally the 2nd gene for any website on which the central is registered. For some sites, the cardinal will go the default 2FA method. Other sites let you rank 2FA methods in society of priority.
