Introducing Two Factor Authentication (2FA) - What is it and why it's important
Twitter's got it. Apple's got it, too. Google, Microsoft, Facebook and Amazon have had it for a while. But why's two-factor authentication important, and will it keep you safe?
What is two-factor authentication?
Two-factor authentication (2FA) adds a second level of authentication to an account log-in.
When you have to enter only your username and one password, that's considered a single-factor authentication.
Two-factor authentication requires the user to have two out of three types of credentials before being able to access an account. The three types are:
- Something you know, such as a personal identification number (PIN), password or a pattern
- Something you have, such as an ATM card, phone, or fob
- Something you are, such as a biometric like a fingerprint or voice print
Two-factor authentication is like a double padlock - it makes it harder for attackers to access your accounts.
2FA means entering your password plus another piece of information, like an access code that has been sent to your phone.
So even if attackers know your password, they can’t get access to your account.
Implementing Two-factor authentication in your business
If you're not sure where to start, think about which systems you connect to via the internet.
Those are the systems that attackers can more easily get access and credentials from.
Because they are easier to target, those are the systems that are most important to protect.
These are likely to be webmail, a VPN or any other cloud-based services.
Important factors to note when considering Two-factor authentication for your business
Two-factor authentication can’t be 'switched on' during or after an attack. Businesses need staff and customers to enable and use 2FA before an attack for it to be effective.
Although 2FA is a great security measure to use, it's not fool proof. You still need to use other good security practices to help keep your information safe.
