From an option that could be activated by those who were genuinely concerned about protecting personal accounts, two-step authentication becomes an essential security criterion, which is active on all Google accounts.

The US giant, Google, announced that it would activate the 2FA (two-factor authentication) function on all of its user accounts after being configured and verified in this regard.

An optional feature so far, 2FA is an additional step to secure online accounts. After entering a username and password while trying to authenticate, the 2FA system sends the user a temporary code on the phone, which he must complete to verify his identity.

In this system, identity verification is done through a personal phone, assuming that a hacker who knows the username and password of an account failed to steal or break his phone, in order to interrupt the verification code.

Before passing on 2FA to all its billions of users, Google will begin a process to verify them. Activation of 2FA will be done only after the notification received by the users on the phone, confirming their identity.

Upon activation, users of Google services will receive a verification code via SMS or a special application. Authentication applications, such as auti, are a more secure option, as SMS is a more sensitive feature.

The safest way to use the 2FA function remains physical authenticity – a small device that can be locked. The codes generated by the physical authenticator do not depend on a wireless connection that is susceptible to interception.
