Managing personal Outlook.com account settings, security, and privacy
Hello JustinC_100,
I'm Ibhadighi and I'd happily help you with your question. In this forum, we are Microsoft consumers just like yourself.
Yes, "https://aka.ms/alca" is a valid redirect link from Microsoft which leads to the account activity page. When someone changes the security settings of a Microsoft account, Microsoft often sends alerts to ensure that the user is aware of the changes, and this link provides quick access to review account activity.
If a phone number or email is added or removed from a Microsoft account, the platform typically sends a notification to the affected number or email as a security measure. I would say the notification might most likely be about the removal and not the addition
If you've had your number for a long time, it's plausible that someone could have mistakenly added your number to their Microsoft account. This can happen especially with recycled numbers or simple human error when typing. It’s also possible that the phone number was added a long time ago and you didn’t notice or remember the notification about the addition. If you’ve had your number for a long time, it’s possible that it was added to another account before Microsoft Account and Gmail were established/popularize
To ensure your security:
- **Do Not Click Links Directly:** Even if a link appears to be legitimate, it's always a good practice to navigate to the website or service directly by typing the URL or using a bookmark, especially if you weren't expecting the message.
- **Check Your Microsoft Account:** Log into your Microsoft account from a trusted device and check the security settings and recent activity. This will give you insights into any changes or suspicious activity.
- **Two-Factor Authentication (2FA):** If you haven't already, consider enabling 2FA for your Microsoft account. This adds an extra layer of security, ensuring that even if someone knows your password, they won't be able to access your account without the second verification method.
I hope this helps.
Best Regards, Ibhadighi
