What is Microsoft unusual sign-in activity?
There could be a number of reasons for a warning about Microsoft unusual sign-in activity, so I've provided a list of the most comment issues below:
- Multiple sign-in attempts.
- Numerous sign-in attempts from different IP addresses.
- Sometimes being signed in on your mobile phone and at home can appear as unusual sign-in activity when you travel to different locations.
- Changes to the account that Microsoft considers suspicious.
- Attempts to hack a profile.
As you can see, there are a variety of reasons for Microsoft to detect unusual sign-in activity on your account, and you may receive a message similar to the one below:
If Microsoft identifies any unusual activity on on your account, including sign-in activity, you will be notified and asked to confirm whether the it was you who was active on the account.
If you confirm that it was you, they will note that they expect you sign in at a certain place (for example, if you're signing in at a hotel). If not, Microsoft will consider that your account has been compromised or hacked, and will provide you with steps to rectify the problem. This usually involves changing your password and updating security information.
