Loading both :database_authenticatable and :two_factor_authenticatable in a model is a security issue It will allow users to bypass two-factor authenticatable due to the way Warden handles cascading strategies! Designing Your Workflowĭevise-Two-Factor only worries about the backend, leaving the details of the integration up to you.
