Upcoming Webinar: Addressing the Risks of SIM Swaps in Passwordless Authentication

On March 17, 2026, Liquid Co., Ltd., headquartered in Tokyo's Chuo district, will host an informative online webinar discussing the threats associated with SIM swaps and effective countermeasures. As passwordless authentication methods like passkeys become increasingly popular, concerns over their security, particularly from SIM swapping and phishing attacks, have risen.

During the webinar, Hideyuki Hoshina, COO of Liquid, will delve into the alarming tactics employed in SIM swapping and outline the potential damages that can arise. He will also offer insights into designing multi-factor authentication (MFA) systems that are resistant to phishing, tailored for various authentication scenarios.

Why Attend?

The perception that implementing passkeys guarantees complete security is misguided and could lead to increased risk. The rise of SIM swap attacks, often stemming from exploiting eSIM reissuance, is now a tangible threat in Japan. These attacks can bypass SMS-based authentication, leading to account recovery breaches and potentially compromising an entire cloud account. Hence, safeguarding through passkeys alone may not suffice if vulernable trails, such as synchronization and account recovery paths, are not secured.

This webinar aims to confront these structural risks head-on. Attendees will learn:

• - Typical Patterns of Online SIM Swaps: Understanding how they operate and the domestic examples.
• - Attack Chains: How SIM swapping can escalate into account recovery breaches leading to financial damage.
• - Risks Associated with Passkeys: Insights into the strengths of passkeys and identifying the risks that still surround synchronization and recovery routes.
• - Designing Phishing-Resistant MFA: Frameworks for implementing resistive multi-factor authentication across four distinct authentication scenarios, including combinations like passkeys, facial recognition, device authentication, and eKYC methods.

Target Audience

This webinar is tailored for:

• - Those who have implemented or are considering adopting passkeys and wish to reassess their security posture.
• - Engineers and project managers responsible for designing or strengthening authentication infrastructure.
• - Security professionals looking to stay updated on the latest SIM swap and account takeover (ATO) techniques.
• - Leaders responsible for services in sectors requiring elevated identity verification standards, including finance, payments, and telecom.

Program Overview

1. Understanding Online SIM Swap Attack Patterns
2. Increasing Dependency and Pitfalls of Syncing Passkeys
3. Phishing-Resistant MFA Design Approaches for Various Authentication Scenarios
