Spotify allows you to log in using multiple methods such as your email and password, Facebook, Google, Apple ID, or even your phone number. You can manage and add different login methods from your Spotify account page for easier access. However, if you signed up with your phone number, note that you cannot use it to log in on the desktop app — it works only on mobile or web. Adding alternative login methods helps ensure you never lose access to your account even if one method faces issues.
