Verbose mode should not print access token

[jeffreywalter]

Although super useful, we have a tendency to copy-paste the entire verbose output into a group chat or forum.
This is probably not a great idea since it includes the access token in the output.
The access token can be used to access the API arbitrarily and should be treated a bit more securely.
I still like the access token to be able to troubleshoot tho. Can we add a -vv or env variable switch or something?

Access token option will no longer be supported: #12.

I don't think #12 actually addresses this issue. An access token will still show up in verbose mode, it will just be the one from the JWT swap rather than a user-provided one. They're both sensitive.
