Two-factor authentication is now automatically enabled for all Google accounts. Here’s everything you need to know about this security measure.

For years, Google has recommended enabling two-factor authentication. The company has now automatically activated it for its nearly 150 million latest users. This is supposed to protect the accounts from access by unauthorised persons.

What are the advantages of two-factor authentication?

Two-factor authentication provides more security; the password alone is not sufficient to log in. The login must be confirmed in an additional step. In light of widespread laziness in dealing with passwords and numerous password leaks, this is a sensible solution. Even if someone knows your password, your account will remain inaccessible to them without additional confirmation. Not just Google, but also many other services, offer this security method.

Why should is it important for your Google account in particular to be secure?

For many people, the Google account serves as a hub on the Internet. In addition to being the login for numerous Google services, it can also be used as a login for non-Google services. It’s where you get codes for two-factor authentication and e-mails allowing you to reset your passwords. Many people also use Google’s integrated password manager. All this information shouldn’t fall into the hands of a stranger.

How does Google’s two-factor authentication work?

What should you look out for when setting up two-factor authentication?

Does two-factor authentication work without a smartphone?

What to do if you lose your smartphone?

Use your backup codes. If you can’t find them, you can also use a new smartphone with a SIM card whose phone number you’ve saved in your Google account. If you haven’t saved your phone number in your Google account, your only option is to contact Google’s customer service. They can reset your account; however, the process can take up to a week.

Can you turn off two-factor authentication?

Yes, you can. Google has two-factor authentication enabled by default, but you can still disable it. You'll find the option in your Google Account settings: go to «Manage your Google Account», then «Security». Under «Signing into Google», you can toggle «2-Step Verification» on and off.

When I was but a young student, I'd sit in my friend's living room with all my classmates and play on his SuperNES. Since then I've had the opportunity to test out all the newest technology for you. I've done reviews at Curved, Computer Bild and Netzwelt, and have now arrived at Galaxus.de.
