- not provided
- Scenario
- Receiving unsolicited SMS messages from a five-digit number claiming to be from Microsoft, complete with a sign-in code and a suspicious link.
- Observed behavior
- Unexpected text messages arrive promoting Microsoft Authenticator and providing a security code, despite the user not attempting to log into their Microsoft account.
Do not click any links or reply to the unexpected text messages, as they may be phishing attempts designed to compromise your account credentials.
Secure your Microsoft account through the official website
The safest way to handle unsolicited security texts is to ignore the message and manually verify your account's security status on the official Microsoft website.
Unsolicited texts with security codes often indicate that someone is attempting to access your account, or it is a phishing scam trying to trick you into clicking a malicious link. Never use the link provided in the text message.
Do not tap any links, call any numbers, or use the security code provided in the unexpected text message. Delete the message or report it as spam.
Open a trusted web browser on your device and type 'account.microsoft.com' directly into the address bar to ensure you are visiting the legitimate Microsoft site.
Log in with your credentials, navigate to the 'Security' tab, and select 'Sign-in activity'. Review this page for any unauthorized or unfamiliar attempts to access your account.
If you notice suspicious activity, immediately change your password to a strong, unique one. Enable or reconfigure multifactor authentication (MFA) using the official Microsoft Authenticator app downloaded directly from your device's official app store.

Frequently Asked Questions
Why did I get a Microsoft single-use code text when I didn't try to log in?
This usually means someone else has your password and is trying to log into your Microsoft account, triggering the two-factor authentication prompt. As long as you do not share the code or approve the prompt, they cannot access your account. You should change your password immediately.
How can I stop receiving these fake Microsoft security texts?
While you cannot completely stop automated bots from sending texts to your phone number, you can block the specific sender or use your phone's built-in spam filter. Alternatively, you can change your Microsoft account sign-in preferences to use a new email alias instead of your phone number.
What happens if I accidentally clicked the link in the text message?
If you clicked the link but did not enter any information on the resulting page, your account is likely still safe. Clear your browser cache and run a quick malware scan on your device. If you did enter your password, go to account.microsoft.com immediately, change your password, and select the option to sign out of all active sessions.
