Best Multi-Factor Authenticators
An alternative to Google Authenticator or Authy
Multi-factor authentication is important because it makes stealing your data more difficult for the average criminal. The less attractive your data is, the more likely thieves are to target someone else. As the name implies, MFA combines at least two separate factors. One is usually your username and password, something you know. The other might be:
Something you have. A cell phone, keycard or USB can all verify your identity.
Something you are. Fingerprints, iris scans or other biometric data prove that you are who you say you are.
Adding this second factor to your username/password protects your privacy. And it is remarkably easy for most people to set up. Sometimes the term two-factor authentication (2FA) is also used.

Physical Security Keys
Physical 2FA keys increase security when logging into websites or performing transactions. These keys add an extra layer of security to the login process in addition to using a password. This makes it much harder for hackers to access accounts because they would also need physical access to the 2FA key. This prevents login information from being stolen via phishing, social engineering or unauthorized access to the user’s device. Physical 2FA keys are therefore a reliable and convenient way to protect online accounts.
