KPN’s MijnKPN service provides customer access to billing, subscription management, and account settings for broadband, television, and mobile services. In 2024, KPN introduced **mandatory two-step verification (2FA)** to improve account security. While 2FA is a common security measure, KPN’s implementation relies exclusively on SMS messages to mobile phones, with **no officially supported landline, email, or hardware token alternatives**.

== | ==Incident== | ||
In early 2024, KPN began enforcing **mandatory SMS-based 2FA for all customers**. Users must enter a one-time code sent to their registered mobile number to access their accounts. Customers without mobile phones, non-Dutch mobile numbers, or with device issues cannot complete the authentication process, effectively restricting access. | |||
Community reports confirm that KPN support advises users in such cases to **obtain a local mobile device** or contact support to regain access. The policy has been systemically applied across the customer base, demonstrating it is a **corporate-wide requirement** rather than isolated incidents.

==Company's response== | |||
KPN has stated that SMS is the **most widely accessible method** for two-step verification and that **other authentication channels are being evaluated**. No public timeline has been provided for the rollout of alternatives such as **landline OTP, app-based authenticators, or hardware tokens**. ([Security.nl](https://beveiliging.headliner.nl/item/kpn-verplicht-2-stapsverificatie-in-augustus-voor-alle-klanten-securitynl-68159)) | |||
==Consumer response== | ==Consumer response== | ||
Community discussions and public forums indicate frustration among users who cannot use SMS, citing **restricted access, lack of alternatives, and reduced consumer autonomy**. Verified responses from KPN moderators confirm the requirement and advise users to acquire a mobile device to comply. The systemic nature of this policy has prompted consumer advocates to call for **multiple authentication channels** to enhance accessibility and security.

==Lawsuit== | |||
No publicly documented litigation regarding this policy has been reported as of 2026. | |||
