How to Sign Out of Prime Video on Fire TV and Switch Accounts
By Miles Kent
Signing out of Prime Video on a Fire TV isn't as simple as tapping a “Log Out” button. Because the Prime Video app is integrated deeply into the Fire TV OS, signing out means deregistering the device from your entire Amazon account.
Keep in mind, using the Deregister button doesn't erase your data. It only disconnects the device from your Amazon account, meaning your purchased movies, shows, and synchronized content will no longer be available on this Fire TV. This step is necessary when you want to switch to a different Amazon account, access another Prime Video library, or log out from shared devices to protect your privacy.
In this guide, you'll learn how to sign out of Prime Video on Fire TV step by step, switch accounts, change profiles, and even access Prime Video content without being signed in.
Part 1. How to Sign Out of Prime Video on Fire TV to Switch Accounts
- To sign out of Prime Video on any Fire TV device, navigate to Settings > Account & Profile Settings > Amazon Account > Deregister. Confirm by clicking Deregister again to unlink the device from your account.

- Selling or Gifting: You are passing your Fire TV Stick or Fire Edition smart TV to a new owner.

Part 4. What Happens When You Log Out of Prime Video?
While Deregistering is a system-level sign-out that changes your entire TV interface and user data, it is important to note that it is not a factory reset. Your hardware settings and third-party files stay intact, while the Amazon-specific features are cleared.
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 |
The Changes You Get After Deregistering (Methods in Part 1 & 2)
If you use the Settings menu or the Remote Sign-Out method, the impact is system-wide because you are severing the link between the hardware and the Amazon Cloud.
- Total Content Disappearance: Your Prime Video library, Watchlist, and purchased movies will disappear from the interface. They are linked to your Amazon profile and you can't access them until you log in again.
- Appstore Lockdown: While you can keep third-party apps like Netflix or YouTube on the Fire Stick, you can't update or download new ones because you lose access to the Amazon Appstore.
- Cloud Safety: Your data stays intact. Amazon saves your search history and preferences. If you log into another Fire TV tomorrow, your entire library will be there.
- Settings Reset: Your Parental Controls, Alexa voice history, and custom Home Screen layouts will be erased.
- The "Clean Slate" Effect: This action clears the system cache, which is why many users do it to fix a laggy Fire TV Stick.
The Changes You Get After Switching Profiles (Method in Part 3)
If you choose to switch profiles instead of a full log-out, the impact is much lower.
- Data Stays Intact: No apps are removed, and the device remains registered to the primary Amazon Account.
- Algorithm Swap: Only your personalized recommendations and "Continue Watching" progress change.
- Billing Remains Active: The primary account holder's credit card remains linked for any In-App Purchases made by any profile.
