“amr” Values spec updated

I’ve updated the Authentication Method Reference Values spec to incorporate feedback received from the OAuth working group. Changes were:

• Added the values “mca” (multiple-channel authentication), “risk” (risk-based authentication), and “user” (user presence test).
• Added citations in the definitions of Windows integrated authentication, knowledge-based authentication, risk-based authentication, multiple-factor authentication, one-time password, and proof-of-possession.
• Alphabetized the values.
• Added Tony Nadalin as an author and added acknowledgements.

The specification is available at:

An HTML formatted version is also available at:
