API summaryMobile Connect Authenticate service – a solution which offers secure user authentication to Service Providers.

Mobile Connect Authentication is defined as two service variants:
• Mobile Connect Authenticate, offering a standard-level of assurance (LoA2 – single factor authentication) via a single user-click or SMS OTP, and
• Mobile Connect Authenticate Plus, offering a higher level of assurance (LoA3 – two factor authentication) by challenging the User for a PIN or biometric

Supporting two different levels of authentication robustness enables SPs to choose the best trade-off between user convenience and security to match their intended use case.

In addition, in situations where the User is accessing the SP over a mobile network, based on IDGW policies the Operator can authenticate the User towards the SP without any User interaction to provide a seamless (zero-click) authentication experience. This special case is considered as single-factor authentication (LoA22).

Two-factor authentication (2FA) is achieved by combining authentication on a mobile device (something I have) with entry of a PIN (something I know) or use of a biometric (e.g. a fingerprint – “something I am”)
LoA2 is based on ISO 29115 standard which is used for single-factor Mobile Connect services.
