Usually there is a way of marking first and second authors, and each discipline has a way of doing this. In your research profile the order of authors should be the same as it was in the published paper.

I did not find a way on ResearchGate, but for your CV or for any Grant application you just write "Author Name and Author Name et al". The concept of shared first or last authorships is very common and happens, if both authors contributed equally in experiment performance and/or ideas during the research process.
Perhaps it is not so often encountered in small journals, but in the big ones (Science , Cell, Nature, PNAS, EMBO) you encounter shared authorships on a regulary basis. Of course during citation only the first author is cited, but for every other use (Grant application, grade evaluation of your PhD, habilitation) a shared first authorship counts for both people as a real first authorship.
A published paper carries the names of the authors in the order given by the authors themselves, and this order should appear wherever this paper is cited.
