Here at Fentons we want to do all we can to ensure our customers network security. Particularly as we are keenly aware that hackers are becoming more prolific and more astute, in their attempts to damage or defraud organisations. They are taking over accounts and accessing data, by discovering passwords or tricking people to divulge them.

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

MFA Security

How does it change access to your data? When you log in, Multi-Factor Authentication prompts you to type a randomly generated code from your phone or to acknowledge a prompt on a separate device, before you’re logged in.

Microsoft state that using Multi-Factor Authentication blocks 99.9% of account hacks. A reassurance, when Microsoft cloud services are seeing 300 million fraudulent sign-in attempts every day.

We are urging all customers to consider deploying MFA to protect their organisation’s Office 365 accounts. It is free to use, as part of subscriptions with Microsoft Office 365 accounts.

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