Each website you create a 2-Factor Authentificaion for also gives you a recovery code that you can use in case you encounter problems with your phone or the Google 2FA app. What is the status of those recovery codes, did you not write them down when you initially set up 2FA?

I have used a few exchanges that allows you to whitelist your device and IP address. The next time you login, it's enough to enter your ID and password and the site wont request a 2FA code. That's why you are still able to access certain sites without any codes.

I was unaware that I was given any recovery codes. Coinbase, for example, simply sent me a verification code so that I could log in, unless this is the code you were talking about. They sent me several such codes, presumably different ones for Coinbase and Coinbase Pro and for the three different devices I was using for access. Of course, I now don't know which code goes with which device or app since they were all texted to my phone and have no differentiating information in the messages.

I guess I won't know anything further until I have occasion to execute a Coinbase/Coinbase Pro transaction. Then I'll just have to see what it asks for and if it is something I can supply.
