Online security has become one of the crucial things that should not be neglected these days due to the high risk of cyber attacks and hacking. The password which you set for your online account or social media app is the first layer of security. But that is not enough, and here is where two factor authentication comes into play. As the name suggests, two-factor authentication offers a second layer of security thus giving a tough time to hackers.
Even if hackers steal your password, they are locked out without the code. Two-factor authentication significantly strengthens your security and has been used commonly by leading websites and apps.
Common Methods of Using Two Factor Authentication
One of the popular ways of using Two Factor Authentication is One Time Code. However, do you know that there are many more authenticator methods? Read about the common methods of using 2 Factor Authentication below.
- Authenticator App
Authenticator apps like Microsoft or Google Authenticator offers a one time code which is time based. However, you have to first link your online account with these apps. Post this, whenever you log in, this app will generate a unique and temporary code to gain access to your account.
- SMS Verification
A one-time code is sent via text message to your registered phone number. You then enter this code on the login page in addition to your password. SMS verification is considered less secure than authenticator apps due to potential vulnerabilities in phone networks.
- Security Key
This physical device plugs into your computer’s USB port or connects wirelessly via Bluetooth. When prompted during login, you press a button on the key to verify your identity. Security keys offer strong protection but require compatible hardware and may not be suitable for all situations.
- Biometric Authentication
Some devices allow using fingerprints, facial recognition, or voice recognition as the second factor. This method relies on your physical features, which cannot be easily replaced if compromised.
Importance of Two Factor Authentication
Two-factor authentication is considered a leading way that can be used to keep the account safe and secure. Read on to learn about the detailed importance of 2FA.
- You can secure your online account using a two factor authentication to add an extra layer of security. Available in different types, one can choose from OTP, authenticator app that works like a second security layer thus protecting the device from breach
- A two-factor authenticator shields your social media accounts like email, social media, and banking. Even if a hacker manages to steal your password, they will be locked out without the additional code generated by your authenticator app.
- 2 Factor Authentication throws a significant roadblock in the path of hackers. Even with your password, they would still need access to your authenticator app to gain entry. This extra layer of protection significantly reduces the risk of unauthorised access and keeps your online life secure
How Does Two Factor Authentication Works?
One of the common methods via which a two-factor authentication works is with the authenticator app. Google and Microsoft have their authenticator app that receives the code when prompted. One has to first enable the 2 Factor Authentication code for their account. Once asked, a code pops up on the mobile app that has to be entered on the screen to log in to the dashboard. Apart from this, physical tokens or biometrics (fingerprint or IRIS scan) are also other ways to do two-factor authentication.
Benefits of Two Factor Authenticators
Know about the top benefits offered by Two Factor Authenticator below.
- Two factor authentication helps prevent unauthorised access to your online account or social media app
- Depending on the method chosen, one is required to enter an OTP or prompt received on the authenticator app
- Even if attackers breach the initial defences (steal your password), they will still not be able to breach your security through the second factor (code from your authenticator app), keeping your accounts secure
- 2 Factor Authentication safeguards your accounts like a high-tech security system. Even if your password is compromised, unauthorised access is prevented. This extra layer grants you peace of mind, knowing your data is shielded and hacker attempts are effectively blocked
Is Two Factor Authentication Secure?
A Two-factor authentication adds an extra layer of security as compared to a single password. However, some considerations can lead to security breaches. For instance, if the hacker gets access to a user’s device then they can easily break the security layer of 2 Factor Authentication. Additionally, the user credentials have to be protected by the user to protect their device.
On a final note, two factor authentication is one of crucial tools that helps to combat cyber attacks elevating the security levels. Depending on the kind of security you need, you can choose a 2FA method for yourself to prevent security breaches.
