Of course, they can be stolen, but some keys have biometrics in them or require another PIN, making it a true MFA key so that even if it’s stolen, people can’t hack into your accounts.
Where physical security keys shine is that they don’t have the issues stated above regarding interception or breaking in. Using Multi-Factor Authentication, or MFA for short, means using more than just one authentication vector, so 2FA is part of MFA. These solutions can have problems though, especially since SMS messages can be intercepted through SIM-swapping attacks, emails can be broken into with social engineering, and authenticator apps lose their value if your phone is stolen or you forget it somewhere. You can receive this code either through an SMS message, an email, or an authenticator app. Typically, 2FA involves receiving a code you have to insert after you enter your password correctly. If you’ve been on the internet, then you’ve probably heard of two-factor authentication, usually abbreviated as 2FA.
