Hotmail's New Security Features
In short, the Hotmail team has added the ability to mark your friend's compromised account as "hacked", opening the door for the Hotmail staff to recover the account, also certain passwords are no longer allowed to be used by users (e.g., "password", "123456", "ilovecats", etc.).
(via The Next Web)
This feature will be introduced for new accounts and when users change their passwords. There is no mention of a prompt, or similar mechanism, to change passwords for those whose passwords are currently insecure. ↩︎
