Security Best Practices for Crypto Users
Crypto security starts with you. Follow these expert tips:
🔐 Enable Two-Factor Authentication (2FA)
Use Google Authenticator (not SMS-only). It generates time-based codes that expire quickly, reducing theft risk.
📱 iPhone users: Search “Google Authenticator” in App Store—verify it’s published by Google LLC.
🚫 Disable Unused API Keys
Hackers often exploit poorly secured API access. If you don’t use API functions (like bots or third-party apps), disable them entirely.
📲 Separate Your Devices: Operation vs Verification
| Device Type | Purpose |
|---|---|
| Operation Device | Used for trading, checking balances |
| Verification Device | Holds authenticator apps, receives SMS/email codes |
⚠️ Never use the same Android device for both! Compromising one app could expose your entire account.
Final Security Setup on OKX
After logging in:
- Tap the menu icon (☰) → Go to User Center
- Click Security Settings
Enable:
- Two-factor authentication
- Anti-phishing code
- App lock (fingerprint/Face ID)
- Device management
Regularly review login history and active sessions.
🔍 As of June 2025, OKX iOS v6.71.1 no longer uses SMS for withdrawals—now requires email + authenticator code. Resetting Google Authenticator requires phone verification first.
