Troubleshooting 2FA, Okta SSO & Account Lockout
⚠️ Account Locked Due to Multiple Failed Attempts
Cause: Security lockout triggered after 3 to 5 consecutive unsuccessful password attempts to safeguard corporate financial data.
Solution: Wait 30 minutes for the automatic security lockout to expire, or contact your internal organization's GIACT Portal Security Administrator to trigger an immediate credential reset.
⚠️ Error 403 Forbidden / Access Denied
Cause: Your connection is originating from an IP address not registered on your company's GIACT whitelisted IP roster.
Solution: Ensure your device is connected to your corporate VPN or accessing from an approved corporate office network. If your company IP changed, your IT security lead must submit an IP update request to GIACT support.
⚠️ MFA Passcode Invalid or Out of Sync
Cause: Time synchronization drift on your mobile device authenticator application.
Solution: Open your authenticator app settings and select 'Sync Time' (Android) or verify that your phone's date and time are set to 'Set Automatically' (iOS). If your phone was replaced, contact GIACT Client Support to re-bind your MFA device.
⚠️ Single Sign-On (SSO) SAML Authentication Loop
Cause: Expired identity provider session cookies in Okta, Ping Identity, or Microsoft Entra ID (Azure AD).
Solution: Log completely out of your corporate identity portal, clear your browser cache and cookies for giact.com and epic.giact.com, and launch the GIACT application chiclet directly from your corporate SSO dashboard.
