You are correct, you'd need to provide the key to each device.
To sign in on a new device you need:
1. Your email
2. Master Password
3. Secret Key
4. The URL for the server your data resides on
When signing in on a new device we offer a variety of ways to help you do this.
1. Your Emergency Kit, a PDF document, has a QR code that can be scanned on most clients.
2. There's also ways to show the same QR code, or a setup code, within the apps to scan on screen
3. For Apple products we do have a method that saves the Secret Key to the Keychain and can sync via iCloud to help facilitate adding the account to new devices
4. You can always do it manually as well
Hope that helps get a better idea of what has to be done there.
