Managing your digital accounts securely has never been more important. Whether you're new to cryptocurrency platforms or looking to strengthen your existing security practices, understanding how to properly manage your account settings is crucial. This guide dives into essential account management and security practices—specifically tailored for users navigating platforms like OKX—while providing clear, actionable steps to help you protect your identity and assets.
From finding your User ID to enabling advanced authentication methods, this comprehensive resource covers everything you need to know about staying safe online in 2025 and beyond.
How to Find Your User ID (UID)
Your User ID (UID) is a unique identifier assigned to your account upon registration. It’s often required when contacting customer support or authorizing third-party services.
To locate your UID:
- Log in to your account.
- Navigate to the Profile or Account Settings section.
- Look for “User Information” or a similar tab—your UID will typically be displayed there.
Keep your UID private and never share it publicly. While it doesn’t grant direct access to your funds, combining it with other compromised data could increase your vulnerability.

Creating and Managing Strong Login Credentials
A strong password is your first line of defense. Avoid using easily guessable information such as birthdays or common words.
Best Practices for Password Management:
- Use at least 12 characters with a mix of uppercase, lowercase, numbers, and symbols.
- Never reuse passwords across different platforms.
- Update your login password regularly—especially after suspicious activity.
If you need to update your password:
- Go to Security Settings.
- Select Change Password.
- Enter your current password and set a new one that meets complexity requirements.
Remember: Even the strongest password isn’t enough on its own. Always pair it with additional layers of authentication.
Enabling Two-Factor Authentication (2FA)
Two-factor authentication adds a critical second layer of security by requiring a time-based code in addition to your password.
You can link an authenticator app like Google Authenticator or Authy:
- Open the app and scan the QR code provided during setup.
- Enter the generated six-digit code into the platform to verify.
- Store recovery codes in a secure location.
⚠️ Warning: If you lose access to your authenticator device, resetting 2FA may require identity verification and take time. Always back up recovery options.
Updating or Resetting 2FA
If you change devices or uninstall the authenticator app, you’ll need to relink it. The process usually involves:
- Logging in with backup codes.
- Verifying your identity via email or SMS.
- Scanning a new QR code to re-enable 2FA.
Avoid disabling cloud sync in apps like Google Authenticator unless absolutely necessary, as this can complicate recovery.
What Is a Sub-Account and How Can It Help You?
A sub-account allows you to create separate profiles under your main account—ideal for team management, trading strategies, or separating personal and investment funds.
Benefits include:
- Granular permission controls (e.g., restrict withdrawals).
- Independent API keys for automated trading bots.
- Clear transaction tracking across multiple use cases.
Sub-accounts inherit the main account’s security settings but can have customized access rights. You can also transfer crypto between them seamlessly.

Using Passkeys for Passwordless Login
Passkeys are a modern, secure alternative to traditional passwords. They use biometric authentication (like fingerprint or face recognition) and are tied directly to your device.
Setting Up Passkeys (App & Web)
On mobile:
- Go to Login Settings > Passkeys.
- Tap “Create Passkey” and authenticate using your device’s biometric system.
- Confirm creation—the passkey is now linked.
On desktop (web):
- Click “Add Passkey” in settings.
- Use a compatible device (e.g., smartphone or hardware key) to confirm.
- Your browser will store the credential securely.
Passkeys eliminate phishing risks since they can’t be copied or reused across sites.
Physical Security Keys: The Ultimate Protection Layer
For maximum security, consider using a physical hardware key like a YubiKey.
These USB or NFC-enabled devices:
- Require physical presence to log in.
- Work with FIDO2/WebAuthn standards.
- Are immune to remote hacking attempts.
Setting one up involves registering the key through your account’s security menu and inserting it whenever prompted during login.
This method is highly recommended for high-value accounts or institutional users.
Authorizing New Devices Safely
Each time you log in from a new device, the system may prompt for authorization. This step ensures only trusted devices gain access.
When prompted:
- Verify the device belongs to you.
- Approve via your authenticator app or SMS code.
- Review active sessions periodically and log out unknown devices.
Never approve login requests you didn’t initiate—this could indicate unauthorized access attempts.

Frequently Asked Questions (FAQ)
Q: Can I recover my account if I lose my authenticator app?
A: Yes, but the process requires identity verification and backup codes. Always save these in a secure offline location before linking 2FA.
Q: Are passkeys safer than passwords?
A: Absolutely. Passkeys are phishing-resistant and tied to specific devices, making them far more secure than traditional credentials.
Q: Do sub-accounts cost anything to create?
A: No—sub-accounts are free and easy to set up, offering flexibility without added fees.
Q: How do I know if a login attempt is legitimate?
A: Check the location, device type, and timestamp shown in your session history. If anything looks unfamiliar, deny access immediately.
Q: Can I use multiple security keys?
A: Yes—you can register more than one physical key for redundancy and convenience across different devices.
Q: Is my UID sensitive information?
A: While not as critical as private keys or passwords, treat your UID with caution—avoid sharing it publicly to reduce exposure risk.
