What is Google Authenticator?


Google Authenticator is a security feature provided by Google. It is a software token that implements two-factor verification services on your mobile phone using TOTP (Time-based One-time Password Algorithm) and HOTP (HMAC-based One-time Password Algorithm).

When you use the Google Authenticator, the app generates a 6-8 digit one-time password that you must enter in addition to your login credentials to access Google services or other apps or websites on your device.

Why is Google Authenticator so Important?

When you add another layer of security to your accounts and it is difficult to hack them. When the two-factor authentication is enabled, a hacker needs more than your login and password to break in; without the unique one-time password, he cannot do so.

The verification codes are unique and change every time you log in and these codes can be used only once. They are sent to your phone via text, voice call or through the Google Authenticator app. You can also choose not to use the Authenticator on safe computers.

This may seem too much of a hassle to many, but it’s also better to err on the side of caution, especially when you are dealing with sensitive account information. If a hacker gets hold of your login details, he can steal your information, or worse delete all your emails, contacts, photos, etc.

He can send malicious emails to your contacts pretending to be you or worse, use your email to reset passwords to your other accounts.

It is a good practice to use strong passwords and change them often, but it is even better to enable two-factor verification for better security.
