What is 2-Step Verification
2-Step Verification (a.k.a. 2-factor authentication) is a security mechanism designed to protect your account from unauthorized access.
If you enable it, nobody will be able to sign in to your Google Account without entering a special verification code from SMS or voice call sent to the specified phone number.
Schematically the authentication process looks like the following:
- You type your login.
- You type your password.
- If the password is typed correctly you receive a security code via call or SMS.
- You type your random verification code
We strongly recommend that you enable 2-Step Verification feature for your Google account!
