Why did I receive an access notification from Yahoo?

If Yahoo detects unusual activity, unsuccessful access attempts, or changes to settings, we'll send a notification to your account and recovery emails. This isn't necessarily a cause for concern. In some situations, someone with a similar Yahoo ID may unknowingly attempt to access an account. If you receive a notification, it's a good idea to check a few things to improve the safety of your account.
