Why do I need to authorize my device?
Coinbase uses Device Verification, a security feature that requires all devices (mobile and computer) and IP addresses to be authorized before accessing your account. This process should only need to be completed once for each device or location.
Authorizing a new device
In order to authorize a device or IP address, click or tap I Authorize This Computer in the email we sent to finish the steps through Coinbase.com. If you didn't receive the email, check your Spam or Trash folders. You might need to add ([email protected]) to your email contacts to prevent our messages from being flagged as spam.
If you use Gmail, they may filter it into the Social or Promotional tabs. You can also search the subject line "New Device Confirmation."
If the link is invalid, or you receive an error message that it has expired, it's likely caused by too many sign in attempts without successfully confirming the device.
Re-authorizing a device
In some cases, you may be prompted to verify a device that has previously been verified. This usually happens if you clear the cache and cookies from your browser after already having verified the device. It can also happen in some cases if you're using a different browser, using your browser's "private browsing" or "incognito" mode, or when using a VPN service or the TOR network.
If this happens, you should be able to quickly verify the device again using the steps listed above. Remember to try only once and wait for the confirmation email to arrive.
