hi Everyone -- curious on what will be the error that I will received if my deployment requires the the 2FA? Is this error possibly related to that? TIA

Are you able to fetch?

extension:deploy

I think he's asking if you're able to fetch because if you're able to fetch then you don't have a 2FA problem. And a 2FA problem will occur if you're using an administrator account that doesn't have the SCDeployer role attached to it.

got it. Thanks... follow-up question, if I use the new extension or theme developer tool, I assumed I do not need to install the patches, correct?

No, the latest ones don't need patching (but you obviously still need to set up TBA as well)

any idea what's that error then? also, where do I put the integration token? I am assuming right now, there is a browser open during my initial fetch/deploy and it's on that pop-up window to where I setup the tokens?

I don't know what the error is about; as for your assumption, I would refer to the documentation

If TBA has been enabled, you can gulp extension:fetch (dash dash) —to to select the target account. You can even create the token via the cli. Even if the patch hasn’t been done, you should be able to fetch..

Thanks Steve & Kearobi! appreciate your time answering my questions.
