Introduction to Coinbase Security Key

Using a security key with Coinbase adds an extra layer of protection to your account. A security key is a physical device that you plug into your computer or connect via NFC, which generates a unique code to verify your identity during login. This method is more secure than traditional two-factor authentication (2FA) because it's resistant to phishing attacks and requires physical possession of the key.

Setting Up a Security Key on Coinbase

To set up a security key on Coinbase, follow these steps:

• Log into your Coinbase account and navigate to the Settings page.
• Click on the Security tab.
• Scroll down to the Two-Factor Authentication section and select Security Key.
• Click Add Security Key.
• Follow the on-screen instructions to connect your security key to your computer. You may need to insert the key or tap it if it's NFC-enabled.
• When prompted, enter a name for your security key to help you identify it later.
• Coinbase will then ask you to confirm the setup by entering a code generated by the security key.

Once the setup is complete, your security key will be linked to your Coinbase account, providing an additional layer of security.

Using Your Security Key to Log In

When you log into Coinbase after setting up your security key, you'll be prompted to use it:

• Enter your email and password as usual.
• You will then be asked to insert or tap your security key.
• The key will generate a unique code that you'll need to confirm your login.

This process ensures that even if someone else knows your password, they won't be able to access your account without the physical security key.

What to Do If You Lose Your Security Key

Losing your security key can be stressful, but there are steps you can take to regain access to your Coinbase account:

• Visit the Coinbase login page and enter your email and password.
• Since you won't have your security key, you'll need to use the backup code you received when you set up the security key. If you've lost this code as well, proceed to the next step.
• Click on I've lost my security key and follow the prompts.
• Coinbase will ask you to verify your identity through other means, such as answering security questions or using a previously set up phone number for SMS verification.
• Once your identity is verified, you can disable the security key from your account and set up a new one or switch to another form of 2FA.

Restoring Your Coinbase Account After Losing Your Security Key

If you've lost both your security key and your backup code, follow these steps to restore your account:

• Contact Coinbase support immediately. Explain your situation and provide any information they request to verify your identity.
• Coinbase support may ask you to provide proof of identity, such as a government-issued ID, to ensure you are the rightful owner of the account.
• Once your identity is confirmed, Coinbase will guide you through the process of disabling the lost security key and setting up a new one or another form of 2FA.
• Follow the instructions provided by Coinbase support to regain access to your account.

Best Practices for Managing Your Security Key

To ensure the safety of your Coinbase account, consider these best practices:

• Keep your security key in a safe place and consider having a backup key stored separately.
• Always keep your backup code in a secure location that you can access if you lose your security key.
• Regularly test your security key to ensure it's working properly and that you remember how to use it.
• Update your security key if it's compromised or if you suspect any unauthorized access attempts.
