Managing online orders from a customer area first requires a seamless login experience. The topic seems simple, but the regulatory requirements governing these interfaces have changed since mid-2025. Enhanced authentication, mandatory accessibility of order tunnels, management of personal data: accessing an online customer area now involves specific technical constraints that directly influence user experience.
Multifactor Authentication and Customer Area: What GDPR Requires Since 2025
The combination of username/password is no longer sufficient when a customer area provides access to payment data or sensitive personal information. The CNIL now relies on Article 32 of the GDPR to require multifactor authentication (MFA) on extranets and customer areas handling such data. Legal analyses published in 2026, based on CNIL deliberation 2025-019 of March 20, 2025, indicate that the absence of MFA can be sanctioned as a security breach.

In practice, when you attempt to log into a customer area to track your orders, modify your delivery information, or view a payment history, a second authentication factor (SMS code, dedicated app, physical key) is increasingly required. This additional layer adds a few seconds to the login process, but it protects your order and payment data from unauthorized access.
For specialized merchant sites, this requirement has a direct impact on the customer journey. On the Nature et Matériaux site, for example, the login page for the customer area allows access to order tracking and management of personal information in compliance with these new requirements.

Digital Accessibility of Order Processes: Obligations Since June 28, 2025
The European directive 2019/882, known as the European Accessibility Act (EAA), came into effect on June 28, 2025, in the 27 member states. It makes digital accessibility mandatory for e-commerce services, online banking, transport, and telecommunications. Customer areas and order processes are explicitly covered by this obligation.
This means that login buttons, order management forms, delivery tracking pages, and payment interfaces must comply with WCAG criteria. A non-compliant customer area exposes the company to sanctions.
What the EAA Changes for the User
From the perspective of the customer managing their online orders, the changes are tangible. Color contrasts on buttons (login, validation, status tracking) must be sufficient. Keyboard navigation must work throughout the entire tunnel, from login to order confirmation. Screen readers must be able to interpret each step of the process.
An accessible customer area is not an ergonomic luxury. It is a legal obligation that applies to all online commerce sites since mid-2025.
Comparison of Connection Methods to a Customer Area
Not all customer areas offer the same access options. Here is a comparison of the most common methods, along with their implications in terms of security and practicality for managing your orders.
| Connection Method | Security | Access Speed | Mobile Compatibility |
|---|---|---|---|
| Email + password only | Low (non-compliant if sensitive data) | Fast | Yes |
| Email + password + SMS code | High | Medium | Yes |
| Login via dedicated app | High | Fast after setup | Yes (native) |
| SSO (Google, Apple, France Connect) | Variable depending on the provider | Very fast | Yes |
| Physical security key (FIDO2) | Very high | Medium | Partial |
The method of email + password + SMS code remains the most common on French merchant sites. It offers a good balance between security and ease of access for checking the status of your orders, modifying a delivery address, or downloading an invoice.

Key Features of a Customer Area for Order Management
Accessing your customer area is only worthwhile if the order management features are genuinely usable. Three points deserve particular attention.
- The real-time order tracking, with updated status (preparation, shipping, delivery), remains the most consulted feature. An effective customer area displays this status right on the homepage after login, without additional navigation.
- Modifying delivery information (address, time slot) after order validation heavily depends on the processing stage. The best-designed customer areas clearly indicate until when modifications are possible.
- Access to payment history and downloadable invoices simplifies accounting management, especially for professional clients who place regular orders for products or materials.
Management of Personal Data from the Customer Area
A customer area compliant with the GDPR must allow you to view, modify, and delete your personal data directly from your interface. This includes your contact details, order history, and communication preferences. The exercise of the right to deletion must be accessible without contacting customer service through another channel.
The ability to export your data (portability) from the customer area becomes a differentiating criterion. Platforms that offer an export button in standard format facilitate switching providers, which enhances customer trust in the management of their information.
Password Security and Best Connection Practices
The strength of your password directly affects the security of your customer area. Current recommendations converge towards long passwords (passphrases) rather than short, complex combinations.
- Use a password manager to generate and store unique credentials for each service
- Always enable two-factor authentication when offered
- Never reuse the same password between your customer area and your email
- Check the URL of the login page before entering your credentials to avoid phishing attempts
These precautions are particularly relevant for customer areas that provide access to payment data or manage orders of high-value products.
Accessing an online customer area now relies on a precise regulatory framework, between mandatory MFA and digital accessibility imposed by the EAA. The choice of connection method, the compliance of the process, and the quality of management features determine whether a customer area truly facilitates order tracking or unnecessarily complicates the experience.
