Control multiple Users with one Client ID

[Jilence]

Hello!

I have following problem. So, I created a Spotify-Application, for the client_id and the client_secret. Then I created a link, that return the auth code. With this code, I create the access token and refresh token.
Now I want to control the Spotify Account, from the User, how clicked on the linked, with my client_id.
BUT, when I click on the link, its working, but when my friends click on the link, it didnt work.

So is this my fault?
