The effect is that the inconvenience is minimized day to day, but you still get increased protection, because the extra step will still be required if anyone tries to sign in to your account from another device.
When you use that service, you won’t be asked for the code because you trust your own phone or your laptop. Some services (including LastPass and Google) allow you to check a box for the service to trust the device that you’re using at that moment – perhaps permanently, perhaps for two weeks or a month. They’ll be asked for the other thing – the text message code or the number from the app on your phone – and they won’t have any way to supply it. If an account is secured by 2FA, then the bad guys can’t get into the account even if they get the password.
When you set up two-factor authentication, your account is still secure even if the password is hacked. When two-factor authentication is turned on for one of your accounts – Google, LastPass, your bank – you have to enter your password, PLUS you have to supply a code sent by SMS or a number generated by an app. It’s similar to Google Authenticator (and fully compatible with all sites that can be set up with Google Authenticator), but it has some significant advantages: Authy can be secured on the phone it can be securely backed up and transferred seamlessly to a new phone and it can be used on a computer. Using an app on your phone is more secure and more convenient than waiting for a code to arrive as a text message.Īuthy is the best way to set up 2FA. From a security perspective, it’s like night and day. The combination of 2FA and a password is far more secure than having just a password, even if the password is complex. The extra thing might be a code sent as a text message to your phone or a number generated by an app on your phone. Two-factor authentication (2FA) adds an extra step to the process of logging into an account – LastPass or your Google account, for example.
But stick with me for a few paragraphs, at least until I get to the geeky details at the end. It’s roughly like having an insurance salesperson look you in the eye and ask you if you’ve thought about what will happen to your family after you’re gone. I know you don’t want to think about this stuff. I want to talk to you about two-factor authentication and why you should use Authy to generate codes on your phone.
