How to Enable Two-factor Authentication – Google and Apple Devices

Two-factor authentication is a type of multi-factor authentication used to add extra security to online accounts. With two-factor authentication, users must complete an extra action in addition to entering a password. A password alone is no longer enough credentials to access an account once two-factor authentication is used. The extra login step may involve logging in using a registered device, responding to an email or text message, answering a phone call, interacting with an app, or inserting physical hardware. One of the easiest 2FA methods is to send a text message to the account holder’s registered phone. Two-factor authentication is also called 2FA or two-factor verification. Multi-factor authentication is also known as MFA.

Passwords are easily stolen. Two-factor authentication ensures the correct people have the appropriate access to information including emails, financial accounts, and corporate information. It can be used to help protect your account from unauthorized access and dramatically increases account security.

Two-factor authentication can be perceived as making the login process cumbersome and difficult. Hardware tokens were one of the first forms of 2FA and involved the user having to keep a FOB with them at all times. With a FOB the user must plug the key into a USB port on a computer. Connecting a phone number to an account or associating a device can be used to receive verification codes by SMS text message or automated phone call. Trusted devices can be associated with accounts and used to verify user identities by displaying a verification code when there is a sign in attempt on another device or browser.
