How to Sign Out of Prime Video on Fire TV
By Miles Kent
Prime Video on Fire TV has no Sign Out button, and no hidden menu will produce one. Unlike the Prime Video app on a Samsung TV, Roku, or iPhone, the Fire TV version has no login of its own — it runs on the Amazon account your entire Fire TV is registered to. That is why the one method that genuinely works for how to sign out of Prime Video on Fire TV is to deregister the device.
- Sign out on the device: Settings > Account & Profile Settings > Amazon Account > Deregister, then choose Deregister again to confirm.
- Faster route: open the Prime Video app, open the left menu, go to Settings > Sign Out, and select Sign Out again. This will automatically take you to the system deregister screen.
- No remote or not at home? Deregister remotely from Manage Your Content and Devices on the Amazon website.

Part 4. What Happens When You Sign Out of Prime Video
If you follow the steps mentioned in the previous sections to sign out, here are the specific changes you will face after you log out of your Prime Video account on Fire TV:
A Quick Comparison: Full Sign Out vs. Switching Profiles
| Feature | After Deregistering (Full Sign Out) | After Switching Profiles |
|---|---|---|
| Watchlist | Completely removed from device | Switched to new user's unique list |
| Purchased Movies | Inaccessible (hidden until new login) | Still accessible (shared by account) |
| Installed Apps | Remain (but cannot update/sync) | Fully functional & accessible |
| Prime Membership | Unlinked from hardware entirely | Stays active for all profiles |
| Data Deletion | Cloud sync & cache are wiped | Nothing is deleted |
| Login Info | Password required to re-access | No password needed to swap |
What Is Removed from the TV?
- The Prime Video library disappears from the interface, along with your Watchlist, until an account is registered again.
- All downloaded video files are wiped. Offline downloads are strictly tied to the active account and will be permanently deleted from local storage upon deregistration.
- The Appstore is locked. You cannot download, open, or update any apps while the device is unregistered.
- Some account-related settings and personal preferences will be removed when the device is deregistered.
What Stays Safe in Your Amazon Account?
Deregistering a Fire TV does not delete anything from your Amazon account. Your Prime membership, purchased movies, rented titles, Watchlist, and viewing history remain associated with your account and become available again after you sign in on another device.
If you sold, lost, or gave away a Fire TV device, deregistering it helps prevent other people from accessing your Amazon services while keeping your content and subscriptions intact.
Part 5. Troubleshooting: When Signing Out Doesn't Work
If you cannot sign out of Prime Video on Fire TV, the issue is usually related to account permissions, device sync, or network connectivity. The table below covers the most common sign-out problems and how to fix them.
| Problem | Why it happens | What to do |
|---|---|---|
| No Deregister option is visible | Some profiles, especially a Kids profile, hide account-level entries. | Switch to the primary profile (far-left profile icon), then return to Settings > Account & Profile Settings. |
| Deregister is greyed out | The device is mid-update, or another operation is still running. | Wait for any progress bar to finish, restart the Fire TV, and try again. |
| I deregistered remotely but the TV is still signed in | The change is queued until the device reaches Amazon's servers. | Leave the Fire TV powered and online; it applies on the next connection. |
| I only want Prime Video off, not the whole Fire TV | Not possible — Prime Video shares the device account. | Use a separate profile for other viewers and leave the account registered. |
