Is any of the Sololearn certificate authentic? Esp, when it's free.

Answer 1

Hey there!
In my opinion, any sort of certificates are authentic but they only add to your profile to a certain extent. It ALWAYS helps to have practical experience to back it up.
In short, think of yourself as an employer, would like to hire a candidate who shows you a certificate that claims he is fit for the job? Or a candidate who can show you his work and prove that he can be valuable to the company?
Hope it helps. Keep on coding! :)

Answer 2

It is authentic my dear but hand-on practice will prove the authenticity
