A Microsoft file hosting and synchronization service.
Microsoft sends verification codes when there is a sign-in or security-related action on the account.
If verification codes are being received every day without being requested, the most common reasons are:
- Someone is trying to sign in to the account
- Another person may be entering the email or phone number by mistake or trying to access the account.
- If the code is not entered, the account remains protected.
- Delayed or repeated delivery of old requests
- A code requested earlier may arrive late, or multiple attempts may cause several messages to be delivered.
Important guidance from Microsoft:
- Do not respond to or use any verification codes that were not requested.
- Treat unexpected codes as a possible sign that someone is trying to access the account.
- Review and strengthen account security (for example, by following the guidance in "How to help keep your Microsoft account secure").
- Consider going passwordless (using Microsoft Authenticator, Windows Hello, SMS/Email codes, or security keys) to improve security and reduce unwanted prompts.
If verification codes or security messages are received by SMS:
- Messages from the short code 69525 or from “Microsoft” can be genuine and are used for security verification codes and account activity alerts.
- If a link is included, genuine Microsoft links in SMS start with aka.ms.
- If a message was not requested, do not click any links; instead, go directly to https://account.microsoft.com or https://account.live.com in a browser to review account activity.
If these unrequested codes continue:
- Sign in to the Microsoft account security page and review recent activity.
- Update security info (phone, email, and sign-in methods) and remove anything not recognized.
- Follow the steps to help keep the account secure and consider enabling passwordless sign-in.
WhatsApp is not used in the provided guidance as an official Microsoft verification channel. Verification codes are sent by SMS, email, or via Microsoft Authenticator and other supported methods.
