We hear you: you want an alternative login option and the truth is, so do we!
An alternative login option has been on our roadmap for a while, but we wanted to make sure we could do it smoothly and safely. Developing it was of our aims this first quarter of 2019, and we're nearly there. A few more weeks of work + testing and we're looking to deliver alt-login circa late April/May.
Until then, however, you can only make a Feeld profile via your primary, active Facebook account.
