First add the Amazon store: [How to add a store](https://merca.getchrovia.com/en/docs/add-store). Then click **Launch** in the desktop app. Set up the passkey in that store's browser window. Don't use the system browser or another store window. Launch the store in the desktop app.

## Open Login & Security

After you sign in to Amazon, open **Login & Security**. On the **Passkey** row, click **Set up**.

## Choose Merca Passkeys

In the dialog, click **Merca Passkeys**. Don't pick another way to save it. If it goes to the phone, iCloud, or another password manager, this store won't have it.

## Confirm it is set up

Amazon shows **Setup complete**. The list may show **Google Password Manager**. That is the passkey you just created.

## Check the store

Go back to the desktop app, open **My stores**, and click **Passkeys** on that store.

The passkey appears in the list, with the site **amazon.com**. If the list is empty, click **Refresh**.

The passkey stays with this store. Later, sign in to Amazon in this store's window to use it. Another store or another browser will not have this passkey. See [Store TOTP and passkeys: storage and access](https://merca.getchrovia.com/en/docs/credential-privacy).
