How do I set up 2-step verification?

Coinbase provides several options for generating 2-step verification codes (AKA 2-factor or multi-factor authentication) with various levels of setup.

What is 2-step verification? 

Security key

Security keys are the most secure method for 2FA. For more information:

TOTP

Duo and Google Authenticator provide a very secure configuration for 2-step verification. These do not require phone reception or internet access once they're set up. Learn how to set up a TOTP authenticator.

SMS text

If you verify a phone number via text message without installing any TOTP authentication apps, you will automatically receive 2FA codes via SMS text message.

Landlines/Voice Call

It is not possible to receive 2FA codes delivered to a landline phone number by voice call. For security purposes, Coinbase does not support the delivery of 2-factor authentication (2FA) codes via voice call. If you have a landline registered with your Coinbase account, follow these steps to upgrade your security:

1. Sign in to the Coinbase website with your username and password
2. Click on the link "Unable to submit one-time code." 
3. Click on "I no longer own the phone number ending in +1 xxx xxx 1234" (as an example)
4. Complete the Account Recovery process by following the steps listed
5. Increase your security by enabling Authenticator
