Enhanced Security

Secure local storage of cloud credentials

We have revised the management of authentication tokens for Box and Google Drive, which were previously retained only while the app was running. These tokens are now stored in an encrypted secure area, and your credentials will be automatically restored even if you restart the app.

  • Reduce the number of unnecessary re-logins

Enhanced OAuth Authentication (PKCE Support)

We have enhanced the authentication flow for cloud connections and now support a more secure authorization method (PKCE).

Key Benefits

  • Reduce the risk of authentication code theft
  • Flexible enough to accommodate future security policy enhancements

Improvements to Token Expiration Management

We have improved the expiration management of access tokens for cloud connections.

  • Reduce sudden errors caused by expired validity periods
  • Improved Stability of Automatic Updates
  • Enhanced reliability during extended use

Improved operability and stability
