You cannot change your Kindle username directly — it is tied to your Amazon account email address
Your Kindle username is the email address associated with your Amazon account. Amazon does not offer a way to change this through Kindle settings alone. If you want a different email address to appear on your Kindle, you have two real options: change the email address on your Amazon account itself, or create a new Amazon account with a different email and transfer your books to it.
The first option — changing your Amazon account email — affects everything tied to that account: your shopping history, payment methods, Prime membership, and all your Kindle books. The second option — creating a new account — means starting fresh with a new library, though you can re-purchase books or contact Amazon to transfer certain titles.
Key Takeaways
- Your Kindle username is your Amazon account email address and cannot be changed separately from it.
- Changing your Amazon email address changes the email on all your accounts and services linked to Amazon, including Prime and payment methods.
- You can change your Amazon email through Account Settings on the Amazon website, not through the Kindle app or device.
- If you want to keep your current email but use a different one on Kindle, you will need to create a second Amazon account.
- Books purchased on one Amazon account do not automatically transfer to another account.
How to change the email address on your Amazon account
Go to amazon.com and sign in. Click on the account icon in the top right corner and select "Account" from the dropdown menu. Look for "Login & security" in the left sidebar. Under "Email address," you will see your current email. Click "Edit" next to it.
Amazon will ask you to enter a new email address and then send a confirmation link to that new address. Check your inbox (and spam folder) for the email from Amazon. Click the confirmation link within the time limit — usually 24 hours. Once confirmed, your Amazon account email changes, and this new email becomes your Kindle username.
This change takes effect when ready on all your devices and apps. Any Kindle device or app you own will now show the new email address as your username. Your books, purchases, and library remain the same.
What happens when you change your Amazon email
Changing your Amazon email address affects more than just Kindle. Your new email becomes the login for your entire Amazon account — shopping, Prime membership, Alexa devices, and anything else connected to that account. You will need to use the new email address to sign in to Amazon.com and any Amazon apps.
If you use your Amazon account to sign in to other services (like some smart home apps or third-party retailers), those connections may break temporarily. You may need to re-authenticate with your new email address. Your payment methods, addresses, and order history all stay attached to the account.
Creating a separate Amazon account if you want to keep your current email
If you do not want to change your main Amazon account email, you can create a second Amazon account with a different email address. This new account will have its own separate Kindle library, wishlist, and purchase history. You can register a Kindle device or app to this second account instead.
To create a new account, go to amazon.com and click "Start here" under the sign-in box. Enter a new email address and create a password. Complete the account setup. You can then register your Kindle device to this new account by going to "Manage Your Content and Devices" on Amazon and adding the device to the new account.
The drawback is that books you bought on your original account will not appear in the new account's library. You would need to re-purchase them or contact Amazon Customer Service to ask about transferring specific titles — Amazon sometimes allows this for certain books, though it is not may provide.
Changing your username on the Kindle device or app itself
The Kindle device and Kindle app do not have a username field you can edit directly. What appears as your "username" is always your Amazon account email. If you open Kindle settings on a device or app, you will see your email address listed, but there is no "change username" option.
If you want a different name to display to other people (for example, in a book club or shared library), that is a different setting. Some Kindle features let you set a display name separate from your email, but this is limited and does not change your actual account username.
Moving books between Amazon accounts
If you create a new Amazon account and want to bring your books with you, you have a few paths. The simplest is to re-purchase books you own — your purchase history on the old account does not transfer, but you can find them again and buy them on the new account. Some publishers offer free re-downloads if you contact them directly with proof of purchase.
For books you own outright (not borrowed or subscribed to through Kindle Unlimited), you can sometimes contact Amazon Customer Service and ask them to transfer a title to your new account. Amazon does not promise this will work, and it depends on the book's licensing terms, but it is worth asking. Have your order number from the original purchase ready.
Borrowed books and Kindle Unlimited titles are tied to the account that borrowed them and cannot be transferred. If you switch accounts, you will lose access to borrowed books on the old account.
Frequently Asked Questions
Can I have two different usernames on two Kindle devices?
Yes. Register one device to your main Amazon account and another device to a second Amazon account. Each device will show a different email address as its username. You can manage both accounts from amazon.com by going to "Manage Your Content and Devices" and selecting which account to view.
Will changing my Amazon email affect my Prime membership?
No. Your Prime membership stays active and attached to your account. The email address changes, but your membership status, benefits, and billing do not. You will just log in with your new email address going forward.
What if I forget to confirm the email change within 24 hours?
The confirmation link expires. You will need to start the email change process again from Account Settings. Go back to "Login & security," click "Edit" next to your email address, and request a new confirmation link.
Can I change my username without changing my email address?
No. Amazon does not separate your Kindle username from your account email. If you want a different username, you must change your email address or create a new account entirely.
Do I lose my books if I change my Amazon email?
No. Your books stay in your library when you change your email address on the same account. They remain yours and appear on all your registered devices. Only if you create a completely new account will you lose access to books from the old account.
