What is Two Factor Authentication?
Normally you enter a platform such as Instagram by putting in your username and password. Eventually if you don’t have a strong password hackers might attempt brute force attack or other methods of stealing your log in information and get access to your account. The Two factor authentication is a way to avoid such security breaches. However, two factor authentication vulnerability should not be overlooked.
Two factor authentication (2FA) provides you with an extra layer of security. Two factor authentication works by asking for information beside your username and password that confirms you are the account owner. This identity confirmation can be done in six ways.
- Code Generator on your device
- Sending a code through SMS to your cell phone
- Security token as a code in physical form
- Encrypted USB drive
- Key fob
- Hardware, a card that needs to be scanned by a card reader
Getting the code via SMS can be insecure based on human error. Should your smartphone gets stolen they can use the code and get access to your account with no trouble. This is a two factor authentication vulnerability. Moreover your codes can be seen on your screen if the notifications are on. Another human error might happen from your phone provider by giving your information to a hacker. The multi-factor authentications cannot avoid malware, man-in-the-middle, phishing or other methods. Therefore they possess a security vulnerability.
Even the authentication apps generating codes can get tricky sometimes. The problem occurs if you reset your smartphone two factory settings. If you don’t save codes or change the method of receiving the codes you’ll be in trouble. So you would have to contact with Instagram helping center or have correspondence via email to get your account back. This might be the most frustrating thinTwo Factor Authentication Vulnerability g to happen to you to see the two factor authentication vulnerability.
On the whole 2FA is a extra level of security yet it does not guarantees complete protection. For instance, in the recent attacks on Instagram accounts, by supposedly Russian hackers, there has been at least one account with two factor authentication security.
