Persona lets you log in to websites using only your email address! Persona lets you prove your identity to websites through your email address without giving them any passwords. This works similarly to how you prove your identity when you show someone your ID: websites can easily verify that your ID is authentic and that you really are the person it was issued to.
Participants are not eligible for an award and are discouraged from submitting a model for the challenge if the participant has an active, signed research partnership agreement with any of the Tox21 partners that provided access to pre-published Tox21 Phase II data (including assay summary activity files, assay description files, concentration response data files, and chemical library and structure files).
NCATS employees are ineligible to register for the challenge. All others are encouraged to participate.
