On January 15, 2012, as a security precaution, we reset and expired the passwords for our customers.
Please click here to create a new password for your Zappos account.
You can read the email that was sent to customers below.
January 15 UPDATE - You can also read the email that our CEO sent to employees about the password change and security incident here.
January 19 UPDATE - For security reasons, we are unable to disclose any specific details about the "cryptographically scrambled" format used for Zappos customers' passwords, aside from confirming that we used a SHA-2 cryptographic hash function.
A SHA-2 cryptographic hash function is a set of cryptographic hash functions designed by the NSA (National Security Agency). When a password is saved in our system, it is altered for the purpose of being unintelligible to other parties. This is what our email to customers was referencing when it stated that "your cryptographically scrambled password (but not your actual password)" was possibly accessed.
We are currently cooperating with the FBI in an ongoing investigation, including undergoing digital forensics. As such, we are unable to provide any additional details about anything related to the investigation.
January 20 UPDATE - We're happy to announce that our phone lines have re-opened! Please feel free to call us 24/7 at 1-800-927-7671.
If you have any additional questions, please email email@example.com
