What is 2FA and why should we use it?
It’s better to be safe than sorry
Hacking a password is fairly easy, but obtaining a physical device that generates the second code or stealing biological features is not as easy, which is why 2FA is one of the most effective security measures available. Securing online accounts is becoming ever so important, and having one barrier of security in place might not be enough to prevent hackers from accessing your data. No matter how strong you make your password, there’s always a chance someone could find it out. Therefore, we recommend implementing two factor authentication to your online accounts.
What is 2FA?
Two factor authentication is an extra layer of security that is known as “multi factor authentication”. Not only does it require a username and password, but something that only, and only, the user has on them i.e. a piece of information the user should know, or have immediate access to, such as a physical token or code. Using a username and password together with a piece of additional information that only the user knows, makes it a lot more difficult for attackers to gain access and steal the users personal data or identity.
How it works
The most common 2FA systems use a unique one time code with every log in attempt. The code is tied to the users account and is typically generated by a token, smartphone or sent to the user via text message. The code normally works for a short period of time (30 seconds), to ensure that only the user themselves have access to it before it could possibly be spread or leaked. This means that even if the attacker knows your account username and password, they still won’t be able to access your information as they won’t have access to the unique code. Once the user enters there username and password, they’ll be prompted with an ‘authentication’ screen, where they’ll usually be asked for the code. Once the user receives the unique code they can enter it and if correct, will have access to their online account.
Why your business needs to implement 2FA
There are various reasons as to why your business needs to implement two factor authentication. If an attacker gains access to just one users online accounts on your business network, they may be able to gain access to everyone else’s depending on the level of authority they have. Introducing 2FA to your business network and the devices on it, may be the best thing your business has implemented in terms of security.
