When you activate a security key as your 2-step verification method on your Coinbase account, you can sign into Coinbase from a computer or through the mobile app. However, it is important that you use a security key that works on both your mobile device and computer. We recommend using a YubiKey because it is a trusted brand that works on both. Learn more about the products they provide based on the type of device you have.

If you set up a security key and try to access your Coinbase account from a mobile browser, note that many mobile browsers do not support security keys—support depends on the browser type and version. Check with your security key manufacturer to ensure they support mobile browsers and your browser developer to find out if they support WebAuthN / Fido2 standard security keys. 3rd-party applications may have restricted functionality.

Keep in mind: 3rd-party apps connected to your Coinbase account might not support security keys. Please contact your 3rd-party application developers for more information.
