Separate account registration from device pairing
U’s help describes registering an account first and then linking the television or streaming device through the on-screen instructions. These are related steps, but they are not the same operation. If the website accepts your account while rejecting the television code, record that distinction before concluding that the account password is wrong.
Read the code currently on the television
The broadcaster says the pairing code contains five letters or numbers without spaces or symbols. It is single-use and is replaced after thirty minutes. A photograph taken earlier may therefore show a code that no longer matches the active pairing screen. Enter the current code carefully and avoid adding spaces copied from a message or note.
Use the same intended account throughout
A shared phone or browser may already be signed into another household member’s account. Check which account is open before linking the television. Otherwise a successful pairing can still produce an unexpected viewing list later. Keep the code private while it is active; it is a temporary instruction for linking your own device, not information to publish in a support forum.
Test the result without unnecessary resets
After following the current on-screen route, check whether the television has moved into the signed-in service. If it has not, note the exact rejection and whether a fresh code appears. A useful support report distinguishes a code-format error, an expired code and a television that does not refresh after acceptance. Reinstalling every app or changing the router password would not isolate those stages.
