FAQs

Google Authenticator will add a formidable layer of protection to your e-mail account? ›

Google Authenticator is a free security app that can protect your accounts against password theft. It's easy to set up and can be used in a process called two-factor authentication (2FA) offered on popular services like Gmail, Facebook, Twitter, Instagram, and more.

2FA is an additional layer of security used to ensure only authenticated users gain access to an online account. Initially, a user will enter their username and a password as usual. Then, rather than gaining access straight away, they will be required to provide additional information.

Alongside the traditional password, users can enter a one-time security code that they receive via text or voice call or that they generate on the Google Authenticator app, which runs on Android and on Apple's mobile operating system iOS. Users can also provide a list of trusted devices within their Google Account.

Backup is cumbersome.

Also, the services often offer reserve codes instead of explicitly suggesting to save the secret. If you lose your secret and log in with a reserve code, you will have to redo the entire TOTP registration process again. Backup codes are sent online, which is often insecure.

Google Authenticator is not directly linked to Gmail, but it can be used to provide two-factor authentication for Google services, including Gmail, if enabled.

Multi-factor authentication acts as an additional layer of security to prevent unauthorized users from accessing these accounts, even when the password has been stolen.

Two-factor authentication provides an additional layer of security by requiring something beyond a password. If a password is compromised, the cyber-criminals will still be unable to access the account without the second factor. This makes it more difficult for attackers to gain access to sensitive information.

Layered authentication is an information security (IS) management technique in which the identity of an individual or system is verified by more than one authentication process. It provides multiple levels of authentication, depending on the underlying transaction, system or operational environment.

What is the secret key in Google Authenticator? ›

After setting up Google Authentication, you are assigned a backup key (secret key). The App then generates one-time passwords (OTP) at regular intervals, using the secret key as a seed. Those one-time passwords are required to log in.

Google Authenticator app is based on the time-based one-time password algorithm where a user inputs a time-based one-time password to verify their identity.

Google Authenticator is a software-based authenticator by Google. It implements multi-factor authentication services using the time-based one-time password (TOTP; specified in RFC 6238) and HMAC-based one-time password (HOTP; specified in RFC 4226), for authenticating users of software applications.

Overview. The Google Authenticator app was chosen because it's free and widely available on Android, iOS/Apple, BlackBerry, or Windows mobile devices, and other third-party APIs/Apps.

When the QR code or manual code has processed, Google Authenticator will generate a six-digit verification code and display it. a. Type the six-digit code you see in the app into the ACF website below the QR code. Then select verify and save.

Key Takeaways

The Google Authenticator 2FA app only secure if you enable Privacy Screen and build in a reliable backup. The most secure 2FA method uses a physical security key, but for a free option, authenticator apps are recommended over text message-based 2FA, which is vulnerable to SIM swap attacks.

2-step verification adds an extra layer of security to your Google Account. In addition to your username and password, you'll enter a code that Google will send you via text or voice message upon signing in.
