Is this genuine?

I have an email from Amazon saying m password has been changed, but in the email it says this message has no content. I know for many other password resets there s always more information on the email so I m curious as to whether what is happening. I have tried to lo in to Amazon and it says error so it obviously has been changed by someone but I don t understand the legitimacy of this email Whigs nothing on it as it looks fake but clearly my password has been hacked and changed
