Last Christmas, my parents got a new Fire TV Stick. My sister got an LG smart TV. My nephew wanted his PlayStation hooked up to Prime Video. Three devices, three living rooms, and me somehow nominated as the family tech person. By the third setup, I could do it in my sleep — but the first one? I wasted twenty minutes going in the wrong direction.
If you landed here because you are staring at a TV screen that says “go to amazon.com/mytv and enter this code,” I want to save you that wasted time. This guide covers exactly what to do, what goes wrong, and the little details Amazon does not bother to explain.
First, Let Me Explain Why Your Phone Is the Right Tool Here
A lot of people instinctively reach for the TV remote when they see a setup screen. That makes sense — the TV is what you are setting up, after all. But amazon.com/mytv is not something you navigate on the TV. It is a website you visit on a separate device.
Your phone is perfect for this. You are already signed into Amazon on your phone. The browser is fast. You can type a six-character code without wanting to throw anything across the room. The whole thing takes about 90 seconds.
There is also a security reason behind this design. If you had to type your Amazon password using a TV remote, anyone in the room could watch you do it. The code system means your actual credentials stay on your phone, where they belong.
What You Need Before You Start
Nothing complicated here. You need your TV or streaming device powered on with Prime Video open — it should be showing you the registration screen with a code. You need your phone with any browser installed. And you need to know which Amazon account you want linked to this device.
That last point matters more than people expect. If you have two Amazon accounts — say, one personal and one for your household — make sure your phone browser is signed into the right one before you start. Registering a device to the wrong account means hunting through settings to fix it later.
How to Do It: Step by Step
That is genuinely it. Most people are surprised by how quick it is once they know not to fight with the TV remote.
The Things That Actually Go Wrong
I have helped enough people through this that I have seen the same handful of problems come up over and over. Here they are, and how to fix them.
A Few Things Worth Knowing
Works on almost every device
Fire TV Sticks, Fire TV Cube, smart TVs from Samsung, LG, Sony, and TCL, Roku, Apple TV, PlayStation 4 and 5, Xbox — they all use this same amazon.com/mytv flow. Once you have done it once, you know how to do it on everything.
International users: check your domain
If your Amazon account is through amazon.co.uk, amazon.de, amazon.ca, or another regional site, your mytv page is at that domain, not amazon.com. So UK users go to amazon.co.uk/mytv. Same process, different starting URL.
You can manage everything afterwards
Once a device is registered, you can rename it, deregister it, or see all your devices by visiting amazon.com/mycd. This is useful if you sell an old TV or give away a Fire Stick — always deregister first so the next owner cannot access your account.
Common Questions
The Short Version
Open Prime Video on your TV. Note the registration code on screen. Pick up your phone, open a browser, go directly to amazon.com/mytv. Sign in with the Amazon account you want. Type the code. Watch your TV update automatically.
The whole thing takes under two minutes. The only real gotcha is making sure you are signed into the right Amazon account on your phone before you start, and moving fast enough that the code does not expire.
After helping my parents, sister, and nephew get set up last month, I can confirm this works the same way on every device and every smart TV I have tried. Once you do it once, it genuinely becomes effortless.
