Amazon.in has a huge bug, which makes it easy to hack. never leave any money in the amazon pay acc. Even after changing the password, and adopting 2 level authentication, it doesnt cause forced logout from all the devices. So, someone who is already loged in through a mobile app, keeps using the acc unauthorised. This small thing Amazon tech team is not getting. I have been trying to explain this since last 7 days, but it hasnt changed anything. beware of using Amazon.in
