Two-factor authentication(2FA) or 2-Step verification is an extra layer of security for your online account,its designed to ensure that you’re the only person who can access your account, even if someone knows your password. It significantly decreases the risk of a hacker accessing your online accounts by combining your password with a second factor, ex. your mobile phone.
With two-factor authentication, your account can only be accessed on devices you trust.Here are the broad steps of how 2FA works :
- When you want to sign in, enter your username and password on sign-in page.
- You would be asked for a second verification step i.e., a six-digit code or a prompt, which you would receive from Google on your phone.
- By entering the code, you’re verifying that you trust the new device.
You won’t be asked for a second verification step again when you sign in from this computer but If you sign in from another computer,you would be asked for a second verification step.
