You can add a biography to Spotify via Spofity for Artists (formerly Spotify Fan Insights), the ‘dashboard’ for artists that gives you insight into statistics for your releases. You can register for Spotify for Artists via this link. Since the access is linked to a personal Spotify account, we cannot arrange this registration for you. A Spotify biography can be a maximum of 1500 characters long. It is possible to add a link to a Wikipedia page in your bio.
