This article is based on the research and observations of Bertrand Karnet, senior online casino specialist and editor-in-chief at JouerEnLigneFR.org, who closely follows the use of biometric tools such as Face ID in French casino applications in order to improve security and user trust.
The convergence of mobile security and online gaming has become one of the most critical issues in the evolution of iOS applications. In France, where gambling regulations are among the strictest in Europe, integrating technologies such as Face ID and Secure Enclave into casino applications 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 across all mobile services, including real-money gambling. As regularly observed by JouerEnLigneFR.org , a leading platform for analyzing online casinos in France, the integration of Apple's biometric authentication systems has become a crucial factor in gaining user trust and meeting compliance standards.
Apple's security architecture and its relevance to gaming applications
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 chosen person unlocking a device via Face ID is approximately 1 in 1,000,000. This level of accuracy surpasses most traditional 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.
Furthermore, Face ID is natively supported by nearly 85% of iPhones active 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 applications.
Regulatory pressures and the rise of biometric adoption in casino applications
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, requiring a local license, geolocation, and strict age verification.
Meanwhile, the ANJ's regulatory framework authorizes a limited number of operators in France, primarily 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 harder for users to trust unverified applications. In this context, biometric security features such as Face ID have become indicators of legitimacy and technological maturity.
Integration of Face ID 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, while the remaining 32% are either under development or in operation without biometric authentication.
Bertrand Karnet, editor-in-chief of JouerEnLigneFR.org, explains that players increasingly view facial recognition as a core feature, not an add-on. As a former casino operator and online gambling strategist, Mr. Karnet has observed that applications offering facial recognition consistently record a lower volume of support tickets related to account access, fewer unauthorized login attempts, and improved session persistence metrics.
He also notes that biometric login is particularly appreciated by users aged 25 to 40, an age group that represents more than 54% of the audience of French mobile casinos according to a joint report by Médiamétrie and 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 indicators between licensed French applications 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 (related to access, for 10,000 users/month) | 24 | 87 |
| Reported fraudulent login attempts (monthly average) | 3,2 | 14,7 |
| Average rating on the App Store (scale of 1 to 5) | 4,6 | 3,8 |
| Unsubscribe rate (average over a rolling 3-month period) | 11,4 % | 18,9 % |
This comparison is based on anonymized data compiled by JouerEnLigneFR.org from public reviews on the App Store and certain 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 loyalty.
Future developments: deeper access keys and authentication layers
In the future, the evolution of Apple's authentication ecosystem is expected to go beyond Face ID. The introduction of Passkeys, which replace passwords with cryptographic keys stored on the device and verified by biometrics, is 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 rate, pressure sensitivity, etc.) to detect anomalies in session behavior. These systems are still in their early stages, but could further enhance 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 gambling infrastructure.
Conclusion: Technology is synonymous with trust
In an industry where reputation can hinge on a single failed login or a 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 where 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 major advantage of casino applications.
