- IG Securities will require Japan clients to enable 2FA by June after phishing attacks.
- Clients who miss the 2FA deadline may face login blocks and account access issues.
- IG Japan also disclosed data issues involving My Number details and client records.
IG Securities will require all Japan clients to activate two-factor authentication by June. The change makes 2FA mandatory after a rise in phishing attacks, and clients who miss the deadline may lose access to their trading accounts during login sessions.
The new rule replaces the broker’s current optional security setup. Clients who have already enabled 2FA will not need to change their login process.
IG Securities Updates Client Security Requirements
IG Securities has advised users to complete the setup before the deadline. The company also warned that support teams may face heavier demand close to the rollout date.
The setup requires an authentication app, such as Google Authenticator or Microsoft Authenticator. Clients must then enable 2FA through the settings section of the IG trading app.
The change comes after IG Japan disclosed recent data handling issues. The company reported two separate cases involving specific personal information, including Japan’s My Number identification data.
One issue involved unauthorized access to customer records by some employees within the wider IG Group. That incident affected 162,879 clients and exposed names, birth dates, addresses, contact details, and My Number data.

IG Securities Reports External Server Data Issue
A second issue involved data linked to 29,734 customers. The information was stored on an external server managed by IG Markets Limited without prior approval from IG Securities.
The company attributed that case to contractor oversight in late January. It did not link the data incidents directly to the new 2FA requirement.
IG Securities is also dealing with a separate product change in Japan. The broker has suspended new vanilla options trades for retail clients three months after launching the service for individual investors.
The firm has not stated that the suspension is tied to security risks. It continues to offer vanilla options to corporate clients, a segment added after the product was expanded beyond retail users.
The 2FA mandate places account protection at the center of IG Securities’ June changes. The broker said clients should act early to avoid delays and possible account access problems.
