From Amazon The sending of a password change notice email to thousands of customers has just been made official. Security issues because they have evidence that their credentials could have been leaked on the network. If you are one of the affected users you have surely received this email, first of all, tell you that it was the company itself that has confirmed the veracity of these emails, if you have believed that it was a kind of fishing or something similar, when entering the website itself with your credentials, you will be forced to change them.
Among Amazon's recommendations for all users, whether or not they are obliged to change their access password, we find that to improve security, this must be unique for the service. Thanks to this, if any database of other services outside the company is stolen, your credentials will not be compromised since the data will be different from this service to that of Amazon itself.
Amazon will force thousands of customers to change their access credentials to the platform.
A very clear example of what Amazon is asking for can be found in the fact that, relatively recently, customers of the Dropbox service and even Netflix were forced to change their access credentials after the password theft suffered by LinkedIn. The main problem was that many of these usernames and passwords were the same for all three servicesHence, any hacker could have access not only to LinkedIn data, but also to a user's Netflix and Dropbox data, which is why Amazon is very concerned.
