This article draws on the research and observations of Bertrand Karnet, senior online casino specialist and editor-in-chief at JouerEnLigneFR.org, who closely monitors the use of biometric tools such as Face ID in French casino apps to improve security and user confidence.
The convergence of mobile security and online gaming has become one of the most critical issues in the evolution of iOS apps. In France, where gambling regulations are among the strictest in Europe, integrating technologies such as Face ID and Secure Enclave into casino apps is not just a technical upgrade, but an operational necessity.
As French users become accustomed to the convenience of biometrics in banking and e-commerce, their expectations are rising in all mobile services, including real-money gaming. As JouerEnLigneFR.org , a leading platform for analyzing online casinos in France, regularly notes, the integration of Apple's biometric authentication systems has become a decisive factor in gaining user trust and meeting compliance standards.
Apple's Security Architecture and Its Relevance to Gaming Apps

Apple's Face ID relies on a combination of software and hardware security. The TrueDepth camera captures a detailed map of the face, which is then processed and stored in the device's Secure Enclave, a dedicated chip segment that isolates sensitive data from the rest of the operating system. This architecture ensures that the biometric template never leaves the device and cannot be accessed by Apple or third-party applications.
According to Apple's official documentation updated in 2024, the statistical probability of a randomly selected person unlocking a device via Face ID is approximately 1 in 1,000,000. This level of accuracy surpasses most conventional login credentials and makes Face ID a compelling authentication mechanism for applications that handle sensitive operations such as deposits, withdrawals, and personal identity verification, which are essential functions of online casino platforms.
Additionally, Face ID is natively supported by nearly 85% of active iPhones in France in the first quarter of 2025, according to mobile operating system usage data published by ARCEP. This widespread compatibility further strengthens its potential as a security standard in mobile casino apps.
Regulatory pressures and the rise of biometrics adoption in casino apps
The French online casino market is shaped by the dual influence of Apple's App Store guidelines and national regulations enforced by the French National Gaming Authority (ANJ). Section 5.3 of Apple's App Review Guidelines restricts gambling apps to native versions, with mandatory local licensing, geolocation, and strict age verification.
Meanwhile, the ANJ's regulatory framework authorizes a limited number of operators in France, mainly for sports betting, horse racing, and poker, while slot machine and roulette apps remain in a legal gray area. As of March 2025, only 17 operators hold a valid license to offer gambling services on mobile platforms.
This strict regulatory framework makes it difficult for international casino brands to enter the French App Store, and even more difficult for users to trust unverified apps. In this context, biometric security features such as Face ID have become a hallmark of legitimacy and technological maturity.
Face ID integration into French casino apps

JouerEnLigneFR.org, a leading French-language authority on regulated online casino platforms, monitors the integration of biometrics across the industry. According to its internal research conducted from January to April 2025, 68% of licensed online casino apps in France offer Face ID or Touch ID functionality, with the remaining 32% either in development or operating without biometric authentication.
Bertrand Karnet, editor-in-chief of JouerEnLigneFR.org, explains that players increasingly view facial recognition as a basic feature, not an add-on. As a former casino operator and online gambling strategist, Karnet has observed that apps offering facial recognition consistently experience lower support ticket volumes related to account access, fewer unauthorized login attempts, and improved session persistence metrics.
He also notes that biometric login is particularly popular with users aged 25 to 40, an age group that represents more than 54% of the French mobile casino audience according to a joint report by Médiamétrie and the ANJ published in 2024.
Comparative analysis of casino apps with and without Face ID support
To illustrate the practical impact of biometric integration, the following table compares key performance and security metrics between licensed French apps that support Face ID and those that do not.
| Indicator | Apps with Face ID | Apps without Face ID |
| Average connection time (in seconds) | 1,8 | 12,6 |
| Support requests (access-related, per 10,000 users/month) | 24 | 87 |
| Fraudulent login attempts reported (monthly average) | 3,2 | 14,7 |
| Average App Store Rating (scale of 1 to 5) | 4,6 | 3,8 |
| Unsubscribe rate (3-month rolling average) | 11,4 % | 18,9 % |
This comparison is based on anonymized data compiled by JouerEnLigneFR.org from public reviews on the App Store and some backend metrics shared by participating operators. While not exhaustive, it highlights a clear trend: apps that implement biometric login not only improve user convenience, but also reduce operational friction and increase user retention.
Future developments: access keys and deeper authentication layers

In the future, Apple's authentication ecosystem is expected to evolve beyond Face ID. Passkeys, which replace passwords with cryptographic keys stored on the device and verified biometrically, are expected to become a common login method for gambling platforms.
Some developers are also exploring multi-level authentication, combining Face ID and behavioral analysis (device movements, typing cadence, pressure sensitivity, etc.) to detect anomalies in session behavior. These systems are still in their early stages, but could further strengthen security without compromising the user experience.
Bertrand Karnet believes that by the end of 2025, biometric login will no longer be just a tool for building trust, but a benchmark for compliance in jurisdictions such as France. He predicts that biometric verification will eventually be integrated into self-exclusion systems and automated limits as part of a responsible gaming infrastructure.
Conclusion: Technology equals trust
In an industry where reputation can depend on a single failed login or compromised user account, the integration of Face ID into French casino apps is more than just an innovation: it demonstrates a commitment to security, compliance, and user-centric design. Apple's biometric ecosystem, combined with French regulatory safeguards, creates an environment in which users can interact with casino platforms with confidence and security.
As JouerEnLigneFR.org continues to examine and monitor the evolution of these technologies, players can rely on its expert advice to identify platforms that meet the new standard and those that are lagging behind. In a context where digital trust is a currency, biometric authentication could well be the key asset for casino apps.
