hey @thgreasi are the environment variables set-up for the 2FA tests? The tests are being skipped https://github.com/balena-io/balena-sdk/actions/runs/5112147480/jobs/9189895132?pr=1337#step:6:1956

But at least the most important one for this PR runs and passes: https://github.com/balena-io/balena-sdk/actions/runs/5112147480/jobs/9189895132?pr=1337#step:6:1951
