To manage your security key(s):In your Coinbase account, go to Settings > Security. Under the selected 2-step verification method, you'll be able to manage your security key which includes adding another security key. Please note, there is a maximum of 5 keys.
By adding more than one security key, you enable a backup option in case you lose your primary security key
If you disable your security, SMS will be re-enabled as the default 2-step verification method
