In the world of cryptocurrency, your UID (User Identification) is a critical piece of information that serves as a unique identifier for your account on platforms like OKX. While sharing certain details like your name or region might seem harmless, disclosing your OKX UID can introduce significant security risks. This guide explains why you should never share your UID and provides practical steps to keep your account secure.
Understanding Your OKX UID
Your OKX UID is a unique numeric code assigned to your account upon registration. It acts as a primary key for accessing your account details, transaction history, and asset holdings. Unlike your username or email, which might be changeable or partially public, your UID is a permanent and sensitive identifier.
Think of it as the digital equivalent of your bank account number—something that should be kept private to prevent unauthorized access.
Key Risks of Sharing Your OKX UID
Account Takeover and Theft
If malicious actors obtain your UID, they may use it to attempt unauthorized access to your account. While alone it may not be enough to log in, it can be combined with other tactics—like phishing or social engineering—to steal your funds, execute trades without your consent, or commit identity fraud.
Targeted Phishing Attacks
Scammers often use UIDs to personalize their phishing attempts. They might send emails or messages pretending to be OKX support, referencing your UID to gain your trust. Once they have your attention, they may trick you into revealing your password, two-factor authentication (2FA) codes, or other sensitive data.
Account Restrictions or Freezing
Sharing your UID with others—especially those engaging in suspicious or prohibited activities—could associate your account with违规 behavior. OKX monitors user activity for signs of fraud or policy violations. If your UID is linked to such actions, your account could be temporarily frozen or restricted, limiting your access to assets and services.
Social Engineering and Impersonation
With your UID in hand, a bad actor might impersonate you when contacting OKX customer service. They could attempt to reset your credentials, bypass security measures, or even request account changes, putting your assets and personal information at risk.
Best Practices to Keep Your OKX UID Secure
Never Share Your UID Publicly
Treat your UID like a password. Avoid sharing it through messaging apps, social media, email, or public forums. Even screenshots that accidentally reveal your UID should be avoided.
Use a Strong and Unique Password
Ensure your OKX account is protected with a strong password that includes uppercase and lowercase letters, numbers, and symbols. Avoid reusing passwords from other platforms.
Enable Two-Factor Authentication (2FA)
Two-factor authentication adds a critical layer of security. Even if someone has your UID and password, they won’t be able to access your account without the second verification step, such as a code from an authenticator app or SMS.
Monitor Account Activity Regularly
Frequently review your login history, withdrawals, and transactions. If you notice any unfamiliar activity, change your password immediately and contact OKX support.
Be Wary of Phishing Attempts
Legitimate companies like OKX will never ask for your UID or password via email or direct message. Always verify the authenticity of any request by contacting support through official channels.
Use a Password Manager
Store your UID and other sensitive credentials in a reputable password manager. This reduces the risk of forgetting or accidentally exposing them.
Avoid Using Public Devices
Refrain from logging into your OKX account on public or shared computers. If you must, ensure you log out completely and never save login information on these devices.
Bookmark the Official OKX Website
To avoid fake websites, always access OKX through your bookmarked official link or the official mobile app.

What to Do If Your UID Is Compromised
If you suspect that your UID has been shared or leaked, take the following steps immediately:
- Change your OKX account password.
- Review and revoke any active sessions in your account settings.
- Confirm that 2FA is enabled and reset it if necessary.
- Contact OKX customer support to report the incident.
- Monitor your account closely for any unusual activity.
Frequently Asked Questions
Is it safe to give my OKX UID to a friend?
No, it is not recommended. Even if you trust the person, sharing your UID increases the risk of accidental exposure or misuse. Keep it private whenever possible.
Can someone withdraw my funds with just my UID?
No, withdrawing funds typically requires your password, 2FA, and possibly email confirmation. However, your UID can be used in targeted attacks to trick you into providing those details.
How can I find my OKX UID if I forget it?
You can usually find your UID in your account settings or profile page after logging in. It may also be shown in transaction confirmations or communications from OKX.
Does OKX support ever ask for my UID?
Official OKX support may ask for your UID to verify your identity in a support ticket you initiated. However, they will never ask for it via unsolicited emails or messages.
What’s the difference between a UID and a username?
A UID is a numeric identifier unique to your account and generally not changeable. A username is often a public, customizable alias that may be used for social features like referrals or community interactions.
Should I hide my UID in screenshots?
Yes. When sharing images of your interface—for example, in tutorials or community posts—always blur or crop out your UID to prevent unintended exposure.
