Unusual Sign-in to Your Account

There’s no doubt at all that Microsoft cares much about users’ account security. The security team has always been working hard to protect all Microsoft accounts, preventing unauthorized sign-in.

What will Microsoft do when discovering an unusual sign-in?

It will send you an email message and an SMS alert whenever a sign-in attempt from a new location/device is detected. Meanwhile, a message will be sent to all your alternate contact methods for security check. This helps greatly to prevent an unauthorized sign-in from new location/device.

Warning: Please remember to take a look at the source of an email or SMS: check the sender, whether it’s Microsoft account team <[email protected]>.

MFA Can Block Over 99.9% of Account Compromise Attacks

Why account protection Microsoft is important?

  • It was reported that over 480,000 Microsoft accounts (0.048% of all accounts) had been infected by spraying attacks in January 2020.
  • And in the same month, there were over 1 million Microsoft accounts breached; that’s to say, over 32,000 compromised accounts were increasing each day.
  • What’s more, there were 300 million fraudulent login attempts every single day.
  • The most horrible news is that according to Microsoft, over 99.9% of all Microsoft account breaches could have been prevented by turning on MFA.

Prevent 99.9% of attacks on your accounts

The MFA offers extra barrier and layer of security to make it much difficult for attackers to get past. There are 2 obstacles to overcome in the implementation of MFA (Multi-factor Authentication).

  1. Users’ misunderstanding; they think external hardware devices are required.
  2. Users’ concerns about potential user disruption or over what it may break.

You should take a leap and go passwordless by enabling MFA. You can enable it for most of your online accounts. The steps to enable MFA for different accounts are different; you should just find the settings menu of an account -> go to the Account or Security section -> turn on MFA by following the on-screen instructions.
