Here at Fentons we do all we can to ensure our customers are cyber safe.

These days, hackers are more prolific than ever with attempts to damage and defraud organisations – they are taking over accounts and accessing data, by discovering passwords or tricking people into divulging them.

Using Multi-Factor Authentication (MFA), also known as 2FA and 2-step verification is one of the easiest and most effective ways to increase the security of your personal identity.

MFA Security

How does it change access to data?

When you log in, Multi-Factor Authentication prompts you to enter a randomly generated code from your phone or to acknowledge a prompt on a separate device, before authenticating your access.

Microsoft say using Multi-Factor Authentication blocks 99.9% of account hacks. Which is reassuring when Microsoft cloud services experience over 300 million fraudulent sign-in attempts per day.

We urge all customers use MFA to protect Microsoft 365 and all internet-based accounts. It is free and part of Microsoft 365 subscriptions.

The easiest verification method for Microsoft 365 is to use the Microsoft Authenticator app. It’s one click instead of typing in a 6-digit code. Also, if you’re travelling, you won’t incur roaming text fees when you use it.
