Managing your digital asset account securely is crucial in today’s fast-evolving cryptocurrency landscape. Whether you're new to OKX or looking to strengthen your account security, understanding key features like user ID retrieval, two-factor authentication, passkeys, subaccounts, and device authorization can make all the difference. This comprehensive guide walks you through essential account management tasks with clear, step-by-step insights—designed to enhance both usability and protection.
We’ve curated the most frequently asked questions from real user experiences, updated for 2025, to help you navigate OKX’s security and account settings confidently. From setting up authenticator apps to transferring crypto between subaccounts, every process is explained with clarity and precision.
How to Find Your User ID (UID)
Your User ID (UID) is a unique identifier assigned to your OKX account. It's often required when contacting customer support or completing identity verification steps.
To locate your UID:
- Log in to your OKX account via the web or mobile app.
- Navigate to Profile > Account Overview.
- Your UID will be displayed at the top of the page, typically as a numeric string.
Keep this information secure and never share it unnecessarily. Unlike passwords or recovery phrases, your UID isn’t sensitive by itself—but combining it with other personal data could increase phishing risks.

Creating and Managing Subaccounts
A subaccount allows you to manage multiple portfolios under one primary OKX account. This feature is ideal for traders who want to separate funds for different strategies, teams, or investment goals.
Benefits of Using Subaccounts:
- Isolate trading activities without creating multiple main accounts
- Assign specific permissions for team members or bots
- Simplify profit tracking and performance analysis
To create a subaccount:
- Go to Assets > Subaccounts.
- Click Create Subaccount and follow the prompts.
- Set transfer limits and access controls as needed.
You can also transfer or deposit crypto between your main and subaccounts seamlessly within the platform interface.
Strengthening Security with Authenticator Apps
Using an authenticator app like Google Authenticator or Authy adds an extra layer of protection beyond SMS-based verification.
How to Link an Authenticator App:
- Go to Security Settings in your OKX profile.
- Select Two-Factor Authentication (2FA) > Authenticator App.
- Scan the QR code with your authenticator app.
- Enter the generated code to confirm setup.
⚠️ Important: Never disable 2FA unless you have a backup method enabled. Store your recovery codes in a secure offline location.
If you ever need to switch authenticator apps, simply go to Change Authenticator App, verify your identity, and re-link using a new device.
Also, consider disabling cloud sync in your authenticator app to prevent unauthorized access through backup files stored online.
Using Passkeys for Faster, Safer Logins
Passkeys are passwordless login credentials that use biometric authentication (like fingerprint or face recognition) and public-key cryptography.
Creating Passkeys on Mobile:
- Open the OKX app and go to Security.
- Tap Passkeys > Create New.
- Authenticate using your device’s biometrics.
- Confirm creation—your passkey is now active.
On Web Browsers:
- Visit OKX Login Page.
- Choose “Continue with Passkey.”
- Follow device prompts to register using Windows Hello, Touch ID, or similar tools.
Passkeys eliminate the risk of phishing and password theft while streamlining access across trusted devices.
Physical Security Keys: Ultimate Protection
For maximum account security, consider using a physical hardware key such as a YubiKey.
This FIDO2-compliant device plugs into your USB port or connects via NFC/Bluetooth, requiring physical presence for login authorization.
Steps to enable:
- Navigate to Security Settings > Physical Security Key.
- Register your key following on-screen instructions.
- Use it during login instead of SMS or app-based codes.
Ideal for high-value accounts or institutional users, physical keys provide tamper-resistant authentication.
Updating Personal Information Securely
Changing Your Email Address
To update your email:
- Go to Account Settings > Email.
- Verify current credentials.
- Enter the new email and confirm via verification link.
Note: You cannot change your email if withdrawals are locked or if there's an ongoing security review.
Updating Your Phone Number
Similarly, changing your mobile number requires:
- Current password
- Existing 2FA method
- Confirmation code sent to the new number
Ensure the new number isn’t already linked to another OKX account.
Authorizing New Devices
When logging in from a new device, OKX prompts you to authorize access for security reasons.
Process Overview:
- After entering your password, select Authorize Device.
Approve via:
- Authenticator app code
- SMS (if enabled)
- Passkey or physical key
- Once approved, the device is trusted unless manually logged out or flagged for suspicious activity.
Regularly review authorized devices and remove any unfamiliar ones immediately.
Freezing Your Account (Web)
If you suspect unauthorized access or lose your phone, freezing your account temporarily blocks all transactions and logins.
How to Freeze via Web:
- Visit the Account Freeze page.
- Enter your UID and complete CAPTCHA.
- Submit a freeze request using registered email or phone.
This action halts trading, withdrawals, and deposits until you unfreeze the account through identity verification.
👉 Learn how freezing your account can prevent unauthorized access in emergencies.
Downloading Account Statements
Track your financial activity by exporting detailed transaction histories.
Available reports include:
- Deposit and withdrawal records
- Trading history
- Funding earnings
- Fee breakdowns
To download:
- Go to Assets > Statements.
- Select date range and report type.
- Click Export CSV.
Use these files for tax reporting, audits, or personal recordkeeping.

Frequently Asked Questions (FAQ)
Q: Can I recover my account if I lose my authenticator app?
Yes—but only if you have backup methods enabled, such as recovery codes, passkeys, or a linked hardware key. Without backups, recovery may not be possible due to security protocols.
Q: Are subaccounts visible to others?
No. Subaccounts are private and only accessible by you or users you explicitly grant permission to. They do not appear in public transaction records.
Q: Is it safe to use SMS for 2FA?
While better than nothing, SMS is vulnerable to SIM-swapping attacks. We strongly recommend using an authenticator app or hardware key instead.
Q: What happens when I freeze my account?
All transactions—trading, withdrawals, deposits—are paused immediately. You’ll need to verify your identity to unfreeze it later.
Q: Can I use multiple passkeys across devices?
Yes. You can register separate passkeys on each trusted device (e.g., phone, laptop). Each uses independent cryptographic keys for enhanced security.
Q: How often should I review my authorized devices?
At least once every three months—or immediately after losing a device or suspecting unauthorized access.
