In today’s digital landscape, security and convenience are more important than ever. With rising concerns over password breaches and phishing attacks, passkeys have emerged as a powerful solution—offering both stronger account protection and a seamless login experience. If you're wondering how to create passkeys, especially for secure platforms like OKX, this guide will walk you through every step, from setup to management.
Passkeys are part of the FIDO2 standard, designed to eliminate passwords entirely. Instead of relying on something you know (like a password), they use something you have (a device or security key) and something you are (biometrics like fingerprint or face recognition). This makes them one of the most secure two-factor authentication methods available today.
What Are Passkeys?
Passkeys allow you to log in without entering a password or waiting for an authentication code. Once enabled, you can use your device’s built-in biometrics—such as Touch ID on Mac, Face ID on iPhone, or Windows Hello—or a physical USB security key to verify your identity.
✅ No passwords to remember
✅ No SMS or app-based 2FA codes
✅ Resistant to phishing and man-in-the-middle attacks
When you activate passkeys on your account, at least one passkey must always remain linked. This ensures your account stays protected at all times. You can add new ones or reset existing ones before removing outdated or unused keys.

How to Create a Passkey: Step-by-Step Guide
Creating a passkey is simple if your device and browser support it. Follow these steps to get started.
Prerequisites
Before setting up a passkey, ensure your setup meets the following requirements:
Device compatibility:
- Windows 10 or later
- macOS Ventura or later
- Or a USB security key that supports the FIDO2 protocol (e.g., YubiKey)
Browser support:
- Google Chrome 109+
- Safari 16+
- Microsoft Edge 109+
Make sure you're logged into your account on a supported browser and device.
Step-by-Step Setup
- Log in to your account at okx.com
- Navigate to Profile > Security > Security Center
- Find the Passkeys option and click Set Up
- Select Enable Passkeys and complete the required security verification
Choose how you want to create your passkey:
- Create with this device
- Use another device or physical key
Option 1: Create with This Device
This method uses your current device’s biometric authentication (fingerprint, face scan) or PIN.
- Click This Device
- Confirm using your device's biometric system (e.g., Touch ID, Face ID)
- Your passkey is created and automatically linked
This is the fastest way to set up a passkey if you're using a modern smartphone or laptop with built-in biometrics.
Option 2: Use Another Device or Physical Key
If you prefer to use a separate device or hardware key, you have two sub-options:
A. USB Security Key
- Select USB Security Key
- Plug in your FIDO2-compliant key (like a YubiKey)
- Follow the on-screen prompts to register it
B. Different Device (Mobile or Tablet)
- Choose A Different Device
- Scan the QR code using your phone or tablet’s native camera
- Complete the authentication using biometrics on that device
This method is ideal for users who want to keep their primary login device separate from their authentication device—adding an extra layer of security.
How to Verify Using a Passkey
Once your passkey is set up, logging in becomes effortless.
Verification on Your Current Device
After entering your username:
- You'll be prompted to verify via biometrics
- For example: “Use Touch ID on your Mac to sign in”
- Complete the scan to access your account
You can still choose Cancel and fall back to password login if needed—but we recommend using passkeys for maximum security.
Verification Using Another Device
If you're logging in from a new or untrusted device:
- Select Verify with another device
- A QR code appears on screen
- Scan it with your registered mobile device
- Confirm login using biometrics on that device
This cross-device verification adds strong protection against unauthorized access—even if someone gains access to your computer.
👉 Skip the password reset hassle—log in securely in seconds with passkeys.
Rename Your Passkey for Easy Identification
As you add more passkeys (for different devices or locations), it helps to give them meaningful names.
To rename a passkey:
- Go to Profile > Security > Security Center > Passkeys > Manage
- Click Rename next to the relevant passkey
- Enter a custom name (e.g., “My Work MacBook” or “Personal iPhone”)
🔔 Note: Renaming only affects how the passkey appears on OKX. To change the actual device name in your browser settings, go to Manage Devices > Linked Devices in Chrome.
Giving descriptive names helps avoid confusion when managing multiple devices—and makes it easier to spot unfamiliar or suspicious entries.
Reset or Remove a Passkey: Security Considerations
There may come a time when you need to remove a lost device or reset your credentials. Here's what you need to know.
Resetting a Passkey
If you only have one passkey linked, you’ll see only the Reset option. Resetting replaces your current key with a new one—it does not leave your account unprotected.
Steps to reset:
- Go to Passkeys > Manage
- Click Reset
- Complete verification (may include facial verification via mobile)
- Create a new passkey following the setup instructions
⚠️ Important: Resetting triggers a 24-hour restriction on withdrawals and P2P trading for security reasons.
Removing a Passkey
You can only remove a passkey if you have more than one active on your account.
To remove:
- Click Remove next to the desired passkey
- Complete verification (using another passkey, 2FA, or facial verification)
- Confirm deletion
❗ Warning: Removing all but one passkey reduces redundancy. Always maintain at least two trusted devices where possible.
Also note: If your account already has 10 passkeys, you must remove one before adding another.
Frequently Asked Questions (FAQ)
Q: Can I use passkeys on multiple devices?
Yes! You can register up to 10 passkeys across different devices—phones, laptops, tablets, or USB keys—for flexibility and backup access.
Q: What happens if I lose my only passkey?
If you lose your sole authentication method, you’ll need to go through account recovery procedures. That’s why it’s wise to register at least two passkeys on separate devices.
Q: Are passkeys safer than SMS-based 2FA?
Absolutely. Unlike SMS codes—which are vulnerable to SIM swapping—passkeys are immune to phishing and interception because they rely on cryptographic authentication tied directly to your device.
Q: Do I still need my password after setting up a passkey?
Yes, in some cases. While many logins will be passwordless, certain actions may still require your password for additional verification.
Q: Will resetting my passkey lock me out?
No—you won’t be locked out, but you will face a 24-hour hold on withdrawals and P2P trading after resetting for security reasons.
Q: Can I use third-party password managers with passkeys?
Some modern password managers (like iCloud Keychain, Google Password Manager) now support syncing passkeys across devices—making management even easier.
Final Thoughts: Embrace the Future of Authentication
Passkeys represent the next evolution in online security—merging ease of use with enterprise-grade protection. By replacing passwords with cryptographic keys and biometrics, they reduce human error and dramatically cut down on account takeover risks.
Whether you're securing a crypto exchange account or protecting personal data, adopting passkeys is a smart move toward a safer digital life.
