AUA/ASA Services


Aadhaar authentication ecosystem has a provision wherein any agency seeking to conduct Aadhaar authentication of its customers/associates etc. for service delivery can engage with an existing AUA (Authentication User Agency). Any agency, which enters into an agreement with AUA is defined as sub-AUA. Any agency seeking to become an AUA directly needs to draw up an agreement with UIDAI.


Authentication Service Agency (ASA) - ASA is any entity that transmits authentication requests to the CIDR on behalf of one or more AUAs. ASA act as enabling intermediaries. They have an established secure connection with the CIDR and convey AUA's authentication requests to the CIDR. ASAs receive CIDR's response and transmit back the same to the AUAs.


An ASA may enter into a formal contract with AUAs. UIDAI has a set of proposed guidelines that may be included in the contract between an ASA and an AUA. However, any contract (and commercial terms, if any) between an ASA and AUA is at the sole discretion of the signing parties, and UIDAI does not have any obligations regarding same.
