Playlist URLs and account sign-ins are different setup methods
Find the correct fields in a trusted player and avoid exposing reusable stream credentials.

Start with the instructions from the authorized source
A playlist URL can point to a list the player fetches. A provider may instead supply a service sign-in with a server and separate account fields. Choose the option the source documents. If the app only accepts one format, ask which supported player works before using a converter.
Understand when an address is private
An address can contain a token or other reusable credential in its query or path. Treat the entire URL as private. A paste into a public forum, a screenshot of the address bar or a shared browser history can reveal access even without a separate password field.
Run one safe first test
Enter the information only in the verified app. Wait for the catalogue to update and open one authorized live feed. If login works but the guide stays empty, check the separate programme source and channel mapping. For support, record the account method and the error text without its secrets.
