Usually three strings and nothing physical. The first is an M3U playlist URL, a single long link that a player loads to build your channel list. The second is a portal address with a username and password, which some players prefer because it also carries VOD folders and account status. The third is an EPG or XMLTV link that fills the program guide. Set-top boxes in the MAG family work differently again: their access is tied to the box's MAC address, registered on the service side, so the box itself becomes the credential. Whichever form you receive, treat it the way you treat a password, because anyone holding it holds your access.

Per stream, and this trips up more people than anything else in setup. Installs and connections are different numbers. You can put the same credentials on a Firestick, a phone, a laptop and a spare TV without limit, because installing costs the service nothing. What costs it bandwidth is playback, so the meter runs on simultaneous streams: 1 to 5 depending on plan. A household of two adults and a teenager typically wants three. Remember that a player left paused or minimized on a phone can still hold a connection open, which is the usual reason a limit appears to be reached with nobody obviously watching.

Because players read credentials differently. Some accept only a playlist URL, some only a portal login, and pasting the wrong form into the wrong field returns an empty list rather than a clear error. Copy and paste rather than retyping, since a single missing character in a long URL fails silently. Two other causes are common: a player that cannot decode HEVC will show audio with a black picture on channels encoded that way, and a list of tens of thousands of channels will make many apps crawl or crash. Most players destabilize somewhere above roughly 18,000 visible channels, so hiding unused groups is a genuine fix.

Assume any link you post publicly is live within minutes. Playlist URLs get scraped from forum posts, screenshots and support tickets, and a shared line shows up as connection-limit errors you did not cause. Never paste your URL into a public thread, blur it in screenshots, and change the password if you have shared it with anyone. If access suddenly behaves as though extra people are on it, ask support to reset the line rather than buying a larger plan. Keep the credentials in a password manager, not in a note on the TV, and remove them from devices you sell or give away.

Buy the smallest paid access and put it through the conditions you actually care about. A $5 trial runs 24 hours, which covers a live event, an evening of VOD and setup on the devices you own. Check three things in that window: whether the guide populates, whether a peak-time stream holds, and how faults scope. One dead channel is a source problem, a whole category failing is server-side, and everything failing points at your own line or session. Plans carry a 7-day money-back window with the trial excluded, nothing renews automatically, and no card is stored after checkout.
