WealthNavi has added Japan’s Public Key Infrastructure, or JPKI, to its smartphone app for identity verification. The change started on February 2, 2026. With this update, people opening an account on the app no longer have to take photos of their face or their ID. They just scan their My Number card with their phone and that is enough to complete verification.
The process uses the electronic certificate stored in the IC chip of the My Number card. This means the verification is based on an official government issued digital certificate. WealthNavi says this makes account opening smoother and also much harder to abuse. Using the IC chip helps prevent impersonation and fraud that can happen with fake or altered ID images. For users who open an account through the WealthNavi website, nothing changes. The existing process using document submission and registered mail will continue.
The JPKI based verification runs on an online identity verification system called LIQUID eKYC. This system is provided by Liquid. WealthNavi says this step fits into a broader effort to tighten security. The company already introduced passkeys with biometric authentication for logins, and this is another layer added on top.

Securities account hijacking has become a growing concern across the industry. WealthNavi says it has not experienced any fraudulent trading so far. Even so, it continues to strengthen both security and ease of use for its roughly 450,000 customers. The company also plans to add stronger protections for sensitive actions like transactions and changes to account information, positioning itself as a secure financial infrastructure service in Japan.
