Con You'll experience a painful process to restore multiple device access
As soon as a device becomes unregistered from Coinbase, it seems to cause a cascade of other devices also complaining and asking or a code. If you're using certain mail providers, Coinbase emails don't even make it to your spam box - they're blocked at the server level. Folks should take care to use a known, white-listed service to ensure you don't lose access to your email resets, or you have to go through a very painful process to restore it. You have to register an entirely new account and follow up with a request for verification. This is all well and good for security's sake, but takes too long.
It can be done much more professionally and quickly if there were secure features to restore device connectivity and access, such as a backup or two step verification with a mobile. This would save days and days, even weeks of lock-out, from what is YOUR money.
