Authorizing the OverDrive app allows you to download Adobe (DRM-protected) eBooks.
You automatically authorize the app when you sign in, regardless of which sign-in option you choose. Learn about which sign-in option is best for you here.
If you download the OverDrive app to multiple devices, be sure to sign into each one with the same account. That way, the authorization will match and you'll be able to download the same eBooks on each device.
