We consider security a top priority. We sent an email that we're updating our authentication policies around third-party email access to better protect Yahoo Mail accounts. You may need to update your account settings in third-party programs to use a more secure approach. Read our help article for more information.

Yahoo Security Notices

We include below links to the text of the emails (in each region) that were sent to Yahoo users beginning on September 22, 2016, December 14, 2016, and October 3, 2017, respectively. The October 3 email is being sent to additional users who have been identified as affected by the data theft Yahoo disclosed in December 2016.

The emails from Yahoo about these issues do not ask you to click on any links or contain attachments and do not request your personal information. If an email you receive about these issues prompts you to click on a link, download an attachment, or asks you for information, the email was not sent by Yahoo and may be an attempt to steal your personal information. Avoid responding to, clicking on links in, or downloading attachments from such suspicious emails.
