The invention discloses a unified identity authentication method and system adopting two factors, belongs to the technical field of identity authentication services, and solves the problem that a conventional unified identity authentication system is insufficient in confidentiality. The method comprises the steps that a user inputs and logs in a first factor, and a system checks and judges whether the first factor logs in successfully or not; the system judges the validity period of the first factor; the user inputs and logs in a second factor, and the system checks and judges whether the second factor is successfully logged in; the system judges the validity period of the second factor; and the system performs a unified identity authentication process. According to the invention, two-factor authentication and unified identity authentication are combined, so that higher security guarantee is provided; and through a strategy of re-login after timeout of the second factor, the potential safety hazard that the e
