When using OKX (formerly OKEx), many users encounter an unexpected message during login: "Your account has exhibited abnormal activity and triggered risk control restrictions. Please verify your identity to proceed." This notification often raises questions: "I just changed my phone/network—why is this flagged as suspicious?"
This article explains why these alerts occur, their connection to device changes, and step-by-step solutions to restore full account functionality.
Common Triggers for "Abnormal Activity" Alerts
OKX employs an intelligent risk-control system to protect accounts. It flags activities that deviate from normal usage patterns, including:
- Device changes: Switching between mobile/PC or using new devices.
- Network anomalies: Rapid IP changes or public WiFi usage.
- Frequent logins: Repeated failed attempts or multi-account switching.
- Unusual transactions: Sudden large transfers/withdrawals.
- Geographic inconsistencies: Logins from locations mismatching KYC data.
These behaviors—though often legitimate—may trigger protective restrictions.
Is This Directly Linked to Device Changes?
Yes. Device changes are a primary trigger. The system detects "device fingerprint" alterations, especially when combined with network switches. Examples include:
- Logging in via mobile 4G in the morning and a different WiFi at night.
- Reinstalling the app or resetting your device.
- Switching browsers or clearing cache for web access.
Such actions may register as "unrecognized device login," prompting security alerts.
Immediate Steps to Resolve the Alert
If you see this message, follow these steps:
- Click "Verify Identity" on the prompt.
Complete one or more of these verifications:
- SMS code (registered mobile).
- Email verification.
- Google Authenticator (if enabled).
- Facial recognition (for high-risk actions).
- Restrictions lift automatically upon successful validation.
The process typically takes minutes, restoring full account access.
Proactive Measures to Avoid Recurring Alerts
Minimize disruptions by:
- Using trusted devices/networks consistently.
- Avoiding frequent device/IP switches (e.g., public WiFi).
- Enabling Google Authenticator and binding email/phone.
- Setting withdrawal whitelists for added security.
These steps build account trust, reducing false triggers.
Troubleshooting Persistent Issues
If verification fails or restrictions persist (e.g., due to rapid trading or system errors):
- Visit OKX Support.
- Submit an "Account Restriction Appeal."
- Provide ID proof and detailed explanations.
- Await resolution (usually within 1–24 hours).
