In case you haven’t already seen this, Wired.com reported late last week that there is a security glitch with some of Amazon passwords.
Apparently, if you signed up several years ago and haven’t ever changed your password, the Amazon system might be accepting close-but-not-exact passwords. Say your password is PASSWORD, the system might also accept PASSWORD12345 or PASSWORDPASSWORD.
The fix is simple: Change your password. You can even change it right back afterwards – that apparently closes the loop.
