If you’ve noticed unusual activity on your account, taking immediate action is crucial to protect your digital assets and personal information. Cyber threats are evolving rapidly, and proactive security measures can make all the difference. This guide walks you through essential steps to regain control and strengthen your account’s defenses—quickly and effectively.
👉 Discover how to lock down your account in minutes with expert-backed security practices.
Change Your Account Password Immediately
One of the first and most critical steps after detecting suspicious behavior is updating your password.
Follow these steps to change your login password on OKX:
- Open the OKX app
- Tap Menu
- Navigate to Profile & Settings
- Select Security
- Choose Login Password and follow the prompts to update it
Best Practices for a Strong Password
- Use a combination of uppercase and lowercase letters, numbers, and special characters
- Avoid reusing passwords—especially those linked to your email or other financial accounts
- Consider using a trusted password manager to generate and store complex credentials
Pro Tip: Clear your browser’s cache and cookies during this process to eliminate any potential session hijacking risks.
A strong, unique password acts as your first line of defense against unauthorized access.
Enable Two-Factor Authentication (2FA)
Two-factor authentication adds an essential layer of protection beyond just a password.
To set up 2FA:
- Go to Security Settings
- Follow the instructions to link your authenticator app (like Google Authenticator or Authy)
Important Notes:
- Always back up the QR code during setup in a secure location—it’s vital if you lose or replace your device
- You can change or disable your authenticator at any time, but be aware: withdrawals will be disabled for 24 hours after any 2FA modification for security reasons
This temporary restriction helps prevent malicious actors from withdrawing funds immediately after compromising your authentication method.

Review and Remove Unauthorized API Keys
API keys allow third-party services to interact with your account. If compromised, they can be used to execute trades or withdraw funds without your knowledge.
To manage your API settings:
- Tap Menu in the app
- Scroll down to Toolbox
- Select API
- Delete any API keys not created by you
Regularly audit your API list—especially if you use trading bots or portfolio trackers—and revoke access from unknown sources immediately.
Manage Trusted Devices
Your account may store data across multiple devices. If one has been compromised, it could provide ongoing access to attackers.
To review device access:
- Visit the Security Center
- Open Device Management
- Remove any unrecognized devices immediately
This step ensures that only devices you currently own and control can access your account.
Update or Remove Payment Methods
Ensure all linked payment methods are accurate and authorized by you—especially in P2P trading environments.
Here’s how to manage them:
- Open the OKX app > Go to Exchange > Tap Menu
- Select P2P Trading
- Go to Profile within the P2P section
- Choose Payment
- View all linked methods under Payment Methods
- Tap Edit to update or Delete to remove unwanted entries
Always confirm changes with a second verification step when prompted.
Delete Unauthorized Verified Addresses
Attackers may add withdrawal addresses during a breach attempt. These can remain dormant until activated later.
On Desktop:
- Log in to your account
- Click Assets in the top menu
- Select Withdraw
- Choose the currency
- Open the Address Book
- Find any verified addresses you didn’t add > Click Delete > Confirm twice
On Mobile:
- Log in > Go to Assets > Tap Withdraw
- Select currency and network
- Open the Address Book
- Swipe left on any suspicious verified address > Tap Delete
Regularly reviewing your address book prevents surprise withdrawals to malicious wallets.
Check and Manage Passkeys
Passkeys offer a modern, phishing-resistant way to log in without passwords.
To review your passkeys:
- Open the OKX app > Tap Menu
- Go to Profile & Settings > Security > Enter the Security Center
- Select Passkeys
Check for any unfamiliar entries. If found, reset your passkey settings immediately.
You can also create new passkeys at any time for supported devices—offering both convenience and enhanced security.
Disconnect Unauthorized Third-Party Login Accounts
Using social logins (Google, Apple ID, Telegram, OKX Wallet) is convenient—but dangerous if unauthorized connections exist.
To manage linked accounts:
- Go to Menu > User Center > Profile
- Find Connected Accounts
- Unlink any third-party services you don’t recognize
This prevents attackers from using compromised external accounts to regain access.
Use a Secure, Trusted Device
All recovery and security actions should be performed on a device you fully trust—one free from malware, spyware, or unauthorized remote access.
If you suspect your current device is compromised, switch to a clean one before making any changes.
Using a secure device minimizes the risk of keystroke logging, screen capturing, or session theft during sensitive operations like password resets or 2FA setup.
Frequently Asked Questions (FAQ)
Q: How quickly should I act after noticing unusual activity?
A: Immediately. Delaying increases the risk of asset loss or permanent account takeover. Begin with changing your password and enabling 2FA right away.
Q: Can I recover funds if a withdrawal was made from my account?
A: Once crypto is sent, transactions are irreversible. However, reporting the incident promptly to official support may help trace suspicious activity or freeze further actions.
Q: Why are withdrawals disabled after changing 2FA?
A: This 24-hour withdrawal suspension is a security measure designed to prevent attackers from changing your 2FA and immediately draining funds.
Q: Are passkeys safer than passwords?
A: Yes. Passkeys use public-key cryptography and are resistant to phishing and replay attacks, making them significantly more secure than traditional passwords.
Q: Should I use the same device for regular use and account recovery?
A: Only if you’re certain it’s secure. For high-risk scenarios, consider using a dedicated, clean device for recovery processes.
Q: How often should I review my security settings?
A: At minimum, perform a full security audit every 90 days—or immediately after any suspected breach.
Taking swift action after detecting unusual account activity can prevent major losses. By updating passwords, securing access with 2FA, auditing APIs and devices, and using trusted hardware, you significantly reduce exposure to threats.
