We are aware of recent emails where users posing as Google or YouTube support have tried to obtain the log-in credentials of our users and partners. Security is a top concern at YouTube and we employ techniques that are both proactive and reactive to block these scams. We are taking additional steps to try to prevent something similar from happening in the future. Also, please note that YouTube will never send an unsolicited message asking for a password or other sensitive information by email or through a link.
Thank you,
The YouTube Team
