2. The assertion includes a description of the authentication requirements placed on the user and can accommodate, as installed on the smartphone, at least AAL2 level of assurance to to the relying party. The app will not run phones without support for key protection.
3. The assertion is signed by an accredited testing body as meeting the highest level of assurance by a recognized accrediting body.
