(Last Updated On: July 16, 2019)

Google Authenticator is a security-based application developed by Google. Don’t we all agree that we need a type of good security on our private accounts? Let it be a smartphone application or a website. We do need some security, So that’s why we all do try to set up a complex password and at times we use the same password for multiple websites.

But yet after setting up a complex password, we also forget these passwords at times. We also tend to entering our accounts in shared or public computers or wifi networks. Such actions may weaken our security. But no worries from now on you can set a normal password which you can remember and criminals won’t get into your account easily.

How does Google Authenticator work?


How does Google Authenticator work

It works on the principal of two-factor authentication that helps to verify the user’s identities before granting them access to certain websites and services. It works even if your account password is stolen or cracked. it works with two steps. (your user name and password + the authentication code). The username and password are always set by you.

The google authenticator works on the principal of one-time password like the usual bank accounts send a message of one-time password on your phone. It is specified in the IETF’s RFC 6238 document. It generates a six-digit code which factors in the current time of day to ensure that each and every code is unique. The authentication code always changes on a specific time factor mostly about 30 seconds.

The two-factor authenticator makes sure that it is less likely that any hacker would pave its way into your account.

The google authenticator has categorised its authentication factors into three factors

1. Knowledge factors


knowledge factor are credentials that the user typically knows, eg. a user name and password. In order to increase the security of your accounts we recommend you to set a username apart from your name. and you can use various password generators to generate a strong password for you. Do use it when you are out of ideas.

2. Possession factors


Possession factors are things that the user has, eg. a mobile phone; In order to get started with two-factor authentication, you need to have a mobile phone with the google authenticator app which is available on both Android and iPhone.

The Inheritance factors are things that the user is eg biometric lock such as a fingerprint or an iris pattern. It can be usually used to protect your phone. Generally so that if anyone steals your phone. So they just cant unlock the phone and go to the google authenticator app.
