What is 2FA?

With so much of our lives happening on mobile devices and laptops, it’s no wonder our digital accounts have become a magnet for criminals.

What is 2FA (two-factor authentication)?

2FA is an extra layer of security used to make sure that people trying to gain access to an online account are who they say they are. That can be typing in a code sent to you by SMS or generated by an app on your phone; it can be plugging in a security key – a special USB stick – to confirm your identity to the website you’re logging into, or it can be confirming that it’s you with a fingerprint or a scan of your face.

Why should I enable 2FA from my online accounts?

It will stop most hacking attempts in their tracks, because the second factor depends on something being with you: your phone, your fingerprint or your security key. When it comes to online banking, from March 2020 banks will need to have introduced a multi-layered approach to logging in, as part of new ‘strong customer authentication’ regulations. Some banks have been doing this for a while, while others have been lagging shamefully behind.

Can I enable 2FA on every website or online account?

Unfortunately not. We think that well-known brands with millions of customers, such as Deliveroo and Netflix, which currently don’t offer 2FA, should do so. Websites that have stored your card details, and email and social media accounts which likely contain a treasure trove of personal data, should be a priority.
