There are several international standards for identity assurance, like NIST (US), eIDAS (Europe, previously STORK) and ISO29115. SURFsecureID is SURFsecureID is based on ISO29115. The four levels of identity assurance commonly used are:
...
- LoA 1: Password authentication through SURFconext at the users home IdP
- LoA 2: LoA 1 + SMS, Tiqr or Tiqr Azure MFA authentication
- LoA 3: LoA 1 + YubiKey (hardware or FIDO2 token ) authentication
Second Factor Only (SFO) authentication
With Second Factor Only (SFO) Authentication "Level" is used to indicate the authentication strength: LoA does not apply. There are two levels:
- Level 2: SMS, Tiqr or Tiqr Azure MFA authentication
- Level 3: YubiKey (hardware or FIDO2 token ) authentication
Level of assurance vs robustness of infrastructure
