Update Multifactor_Authentication_Cheat_Sheet.md (#1248)

* Update Multifactor_Authentication_Cheat_Sheet.md

Updated biometric information, as it has become commonly available through webauthn.  I think it would make sense to add a cheatsheet on webauthn, but I didn't want to be presumptive.

* Update Multifactor_Authentication_Cheat_Sheet.md

Removed webauthn reference.  Probably should have a webauthn page that could cover biometrics and webauthn and their relationship.

 - Require manual enrolment of the user's physical attributes.

 - Privacy concerns: Sensitive physical information must be stored about users.
 - If compromised, biometric data can be difficult to change.
