This multi-factor profile is an extension to REFEDS Multi-Factor Authentication (MFA) Profile (https://refeds.org/profile/mfa)[1], applicable for Swedish Higher Education.

...

The Member organisation MUST be certified for SWAMID Identity Assurance Level 2 Profile [2].

Only subjects currently at SWAMID Identity Assurance Level 2 are allowed to authenticate themselves according to this Profile.

...

•  Choice of multi-factor technology MUST be documented in section 5.1 Credential Operating Environment.
  
  The selected second factor or full multi-factor solution MUST be based on the Single-Factor and Multi-Factor Authenticator Types within NIST 800-63B [3].
  
  Guidance: SWAMID has published a set of valid choices for second factor and full multi-factor solutions in the SWAMID wiki.
  
  

• Processes for issuing and assigning of credentials (second factor or full multi-factor) MUST be documented in 5.2 Credential Issuing (more precisely in 5.2.5).

  Issuing of second factor or full multi-factor MUST be done using one of the following methods

  1. 1. On-line multi-factor authenticating the Subject with SWAMID MFA Profile or higher level using an external Identity Provider compliant with SWAMID MFA Profile or higher

     2. In-person visit at a service desk in combination with identity proofing as defined by the Swedish Tax Agency for issuance of the Swedish Tax Agency identity card

     3. In-person visit at a service desk in combination with identity proofing with an international passport fulfilling ICAO Doc 9303 International Civil Aviation Organization (ICAO) Doc 9303 Machine Readable Travel Documents [4], an EU/EES national identity card fulfilling the Regulation (EU) 2016/399 of the European Parliament and of the Council [5] or an EU/EES driving license fulfilling the Directive 2006/126/EC of the European Parliament and of the Council of 20 December 2006 on driving licences [6].

     4. Off-line using a certified mail to a postal address (sv. rekommenderat brev med personlig utlämning) in combination with a time-limited one time password/pin code.

     5. Off-line using a certified mail to a postal address (sv. rekommenderat brev med personlig utlämning) with a preregistered device, unique for the user, that will be considered as a vetted token on first use.

  
  Guidance: The second factor or full multi-factor must be issued separately to to the user credentials in accordance with the REFEDS MFA Profile criteria.
  
  Guidance a: Multi-Factor solutions provided within the Swedish E-identification system fulfils the requirements for on-line multi-factor authentication and can be used for online identity vetting if allowed by the E-identification issuer. Likewise, authentication via eIDAS with assurance level substantial or high fulfils the requirements.
  
  

• Processes for replacement of additional factors or full multi-factor MUST be documented in 5.3 Credential Renewal and Re-issuing.
  
  Replacement of second factor or full multi-factor MUST be done using the same methods as listed above for Credential Issuing.
  
  
• Processes for revocation of second factor or full multi-factor MUST be documented in 5.4 Credential Revokation

...

• The authentication of the user’s current session used a combination of at least two of the four distinct types of factors defined in ITU-T X.1254: Entity authentication assurance framework, section 3.1.3, authentication factor (something you know, something you have, something you are, something you do) [4].
• The factors used are independent, in that access to one factor does not by itself grant access to other factors.
• The combination of the factors mitigates single-factor only risks related to non-real-time attacks such as phishing, offline cracking, online guessing and theft of a (single) factor.
