Google Authenticator can help secure your login access to any website or service. It’s a 2FA app that allows you to log in only using the 2FA code given by the app. Here’s how to set up Google Authenticator.
You know that two-factor authentication is way safer than an SMS message. That’s why there’s an app like Google Authenticator and it is getting more popular. But if you don’t know how it works, you can learn it in summary here.
How two-factor authentication works
Two-factor authentication is a replacement for SMS verification. The difference is that two-factor authentication using an app like Google Authenticator uses a verification code that only lasts 30 seconds then generates again for every 30 seconds.
Google Authenticator can be used to any serviced or website, as long as the website or service itself supports it. Once you logged in to a website, you have to put the 2FA code generated on the Google Authenticator as soon as possible.
