Verify Microsoft Account Sign-in Activity Manually

Instead of clicking the link from the text message, navigate to the official Microsoft website directly through your browser to safely check for unauthorized access.

While aka.ms is a legitimate Microsoft URL shortener and aka.ms/alca typically redirects to the account sign-in activity page, spoofing can occur. The safest approach to any security alert is to bypass the provided link entirely and access your account dashboard manually.

1
Go to the official Microsoft website

Open your preferred web browser and type account.microsoft.com directly into the address bar.

2
Sign in to your account

Enter your Microsoft account email and password to log in securely.

3
Access security settings

Click on the 'Security' tab located in the top navigation menu of your account dashboard.

4
Review sign-in activity

Select 'Sign-in activity' to view a list of recent logins. If you see unfamiliar locations or devices that match the time of the text message, secure your account immediately by changing your password.

Frequently Asked Questions

Why did I receive a text message with aka.ms/alca?

You likely received this automated alert because Microsoft detected unusual login activity on your account, or someone attempted to sign in from a new device or location.

Is aka.ms a scam or phishing website?

No, aka.ms is a legitimate URL shortener owned by Microsoft. However, scammers can sometimes spoof the sender name in a text message, which is why it is always safer to navigate to account.microsoft.com manually rather than clicking the link.

What should I do if I accidentally clicked the suspicious link?

If you clicked the link but did not enter your password, your account is likely safe. If you did enter your login credentials, immediately go to account.microsoft.com manually, change your password, and enable two-factor authentication (2FA) to secure your account.
