Authenticator autorisation suspect

Question

Bonjour, L'accès à mon coffre-fort je reçois une demande de DIN7L pour valider L'accès via authenticator. Est-ce normal ? Merci pour votre aide.

Answer 1

Hello Raynal ARIAS, thanks for posting this in our community.

Microsoft Authenticator prompts are triggered when someone attempts to sign in to your account using your credentials. If you did not initiate this sign-in, it could indicate that someone else has your username and password or that there is a phishing attempt or compromised credentials.

Do not approve the request unless you are certain it was you. Change your password immediately by going to Microsoft Account Security and using a strong, unique password. After that, check your recent activity in the same security page to review any suspicious sign-ins.

To strengthen your account security, make sure Multi-Factor Authentication (MFA) is enabled for all accounts, turn on sign-in notifications in Microsoft Authenticator, and consider enabling passwordless sign-in for added protection.

Regarding the device name DIN7L, this is likely the hostname of the device requesting access. If you do not recognize it, treat it as suspicious and remove any unknown devices from your account by going to the Devices section in your Microsoft account settings and unlinking unfamiliar ones.

Hope this helps.

Kind regards,

John Oli

Answer 2

Receiving a request for authorization via the Microsoft Authenticator app, such as the one you mentioned (DIN7L), is a normal part of the multifactor authentication (MFA) process. This is designed to enhance security by requiring a second form of verification when accessing sensitive accounts or data. If you initiated the sign-in process, then it is expected to receive such a request. However, if you did not attempt to access your account, it could indicate a potential unauthorized access attempt. In that case, it is advisable to deny the request and review your account security settings.

Make sure to check for any suspicious activity on your account and consider changing your password if you suspect unauthorized access.
