Hardware security keys are becoming more widely accepted by services. It's possible to sign in to a Google or Microsoft account by receiving notifications on a trusted device. Services that allow two-factor authentication (but not all) offer a variety of authentication methods. They can't continue the sign-in process without the code. Were it, someone who had stolen my Google account credentials, they would be halted in their tracks.

Two-factor authentication (also known as 2FA) requires second evidence of identity, such as a code from an authenticator app. When I went to sign in to my Gmail account from a browser I had never used before, this is what I saw. In order to obtain that code, you have two options: From the service or generated by an app loaded on your phone.

Due to their popularity, smartphones make excellent security gadgets.Īssist with authentication by using your smartphone to generate a unique code that you enter together with your password to log in. There is 'something you know,' such as a password, PIN, fingerprint, or other biometric ID, as well as 'something you have,' such as a trusted smartphone that can produce and receive confirmation codes, or a hardware-based security deviceįirst (your password) and second (your PIN) are the most common two-factor authentication methods in use today (your smartphone). They can be derived from a combination of at least two elements, including: In most cases, you can choose to mark the device as trusted once you've successfully completed that challenge, which means that 2FA requests should be rare for the devices you use often. It alters the security requirements so that when accessing a secure service for the first time on an unknown device, it requires at least two proofs of identity. HOW DOES 2FA WORK? ISN'T IT INCONVENIENT? Many people have asked me about two-factor authentication (often known as two-factor authentication or 2FA). Google's own 2019 research came to similar conclusions. Multi-factor authentication, even if it's just SMS-based one-time passwords, is recommended by Microsoft if the service provider offers it. It found that 2FA is effective in blocking 99.9 percent of computerized assaults. This is according to a Microsoft analysis from 2019. There are other services that name it multi-factor authentication or two-step verification, but 2FA is the most generally used phrase, so I'm going to stay with it.) Two-factor authentication (often known as 2FA) is the answer. Even knowledgeable people can be duped into entering their credentials on a phishing site or divulging them over the phone through social engineering. However, even if you have appropriate security measures in place (complexity, changing them periodically, and not reusing them), people are still the weakest link. While it's possible to construct an extremely difficult-to-type password, it won't do you any good if the service where you use that password stores it incorrectly and then gets their server compromised.
Unfortunately, passwords are a fatally insecure method of protecting valuable resources.Ī longer, more complex, harder-to-guess password doesn't automatically make you more secure online. One data breach might turn your online existence upside down.
