Using multi factor authentication for all your devices




“Two-factor authentication is the key to keeping your digital life secure. Embrace it and it will save you in the long run!” 



Two Factor Authentication (2FA) is proving to be one of the most secure ways to protect against cyber-attacks. By requiring a second layer of authentication, such as a one-time code sent via SMS or email, 2FA ensures that even if an attacker obtains the password for an account, they will not be able to access information without also having possession of the user’s phone or computer. This extra step makes it much more difficult for hackers to gain access and can help prevent data breaches and identity theft.  


For businesses, implementing 2FA can help protect confidential customer data and employee records from being stolen. It also adds an extra layer of security for password resets and other sensitive activities, which can stop attackers from exploiting weaknesses in passwords or manipulating security protocols. 



The method leverages two different forms of authentication, such as something the person knows (like a password) and something the person possesses (like an identification card or phone). As 2FA requires both components to log in, it drastically cuts down on the chances of a brute force attack.  


Brute force attacks are one of the most common tactics used by hackers to gain access to accounts; they involve using automated software that systematically tries every possible combination until it successfully guesses the correct password. With 2FA in place, even if someone were able to guess your password, they would still need another form of verification—such as a secondary code sent via text message—to get into your account. This makes it virtually impossible for someone to break into your account without having both pieces of information. 



3 Ways you can use 2FA to secure yourself  


  • Sms- Text.  

SMS 2fa, an authentication feature that uses text messages to verify a user’s identity, is a widely used form of security. While this method can help protect a user’s account from unauthorized access, it can also be easily compromised by hackers. 


Experts have warned that SMS 2fa is not secure and should not be relied upon for strong authentication methods. This is because text messages are sent over cellular networks and are vulnerable to interception or spoofing by malicious actors who may want to gain unauthorized access to accounts. Furthermore, the codes used in SMS 2fa can expire quickly due to network latency or other technical issues which could leave your accounts exposed if they are not updated regularly. 


To reduce risk of security breaches caused by SMS 2fa, users should opt for more advanced authentication systems such as biometrics or hardware-based tokens. 


  • Biometric  

Biometric security is becoming an increasingly popular form of two-factor authentication (2FA) as businesses and individuals seek to better protect sensitive data. Two of the most common biometric securities used are facial recognition and fingerprints. Facial recognition technology uses images, such as a photograph or video, to recognize a person based on facial features, while fingerprint identification systems capture fingerprints from a live scan of the person.  


By enabling users to log into their accounts using the unique elements of their face or fingerprints instead of passwords, biometrics can provide an additional layer of authentication that is more secure than traditional passwords alone. This method ensures only authorized people have access to protected data by verifying personal identifiers that cannot be easily replicated by third parties. It also makes it difficult for unauthorized personnel to access personal information even if they were able to obtain passwords and usernames from other sources. 


  • USB/ Physical Key 

One of the most secure ways to protect your data and access accounts is with a physical key. USB 2fa security keys offer an extra layer of protection by preventing cybercriminals from accessing user accounts. Now, having a physical key that you keep on your key ring at all times is becoming even more convenient.  


The latest technology in physical security allows users to carry their own personal USB 2fa security keys right on their key ring for easy access. This eliminates the need for carrying around special cards or other items that are used for authentication purposes. Furthermore, it prevents unauthorized individuals from accessing user data if they do not have the key in their possession.  


This type of physical security can be utilized with many popular online services such as Google, Microsoft, Apple and Facebook that support two-factor authentication (2FA). 



In conclusion, two-factor authentication can be an effective tool in protecting your online accounts, data, and identity. It is important to select the option that works best for you and your needs.
