The OpenID Foundation (OIDF) promotes, protects and nurtures the OpenID community and technologies. As a non-profit international standardizing body, it is comprised by over 160 participating entities (workgroup participants). The work of preparing implementer drafts and final international standards is carried out through OIDF workgroups in accordance with the OpenID Process. Participants interested in a subject for which a workgroup has been established have the right to be represented in that workgroup. International organizations, governmental and non-governmental, in liaison with OIDF, also take part in the work. OIDF collaborates closely with other standardizing bodies in the related fields.
Final drafts adopted by the Workgroup through consensus are circulated publicly for the public review for 60 days and for the OIDF members for voting. Publication as an OIDF Standard requires approval by at least 50 % of the members casting a vote. There is a possibility that some of the elements of this document may be the subject to patent rights. OIDF shall not be held responsible for identifying any or all such patent rights.
Financial-grade API Security Profile 1.0 consists of the following parts:
These parts are intended to be used with RFC6749, RFC6750, RFC7636, and OIDC.
The Financial-grade API is a highly secured OAuth profile that aims to provide specific implementation guidelines for security and interoperability. The Financial-grade API security profile can be applied to APIs in any market area that requires a higher level of security than provided by standard OAuth or OpenID Connect. Among other security enhancements, this specification provides a secure alternative to screen scraping. Screen scraping accesses user's data and functions by impresonating a user through password sharing. This brittle, inefficient, and insecure practice creates security vulnerabilities which require financial institutions to allow what appears to be an automated attack against their applications.
This document is Part 2 of FAPI Security Profile 1.0 that specifies an advanced security profile of OAuth that is suitable to be used for protecting APIs with high inherent risk. Examples include APIs that give access to highly sensitive data or that can be used to trigger financial transactions (e.g., payment initiation). This document specifies the controls against attacks such as: authorization request tampering, authorization response tampering including code injection, state injection, and token request phishing. Additional details are available in the security considerations section.
Although it is possible to code an OpenID Provider and Relying Party from first principles using this specification, the main audience for this specification is parties who already have a certified implementation of OpenID Connect and want to achieve a higher level of security. Implementers are encouraged to understand the security considerations contained in Section 8.7 before embarking on a 'from scratch' implementation.
The keywords "shall", "shall not", "should", "should not", "may", and "can" in this document are to be interpreted as described in ISO Directive Part 2. These keywords are not used as dictionary terms such that any occurrence of them shall be interpreted as keywords and are not to be interpreted with their natural language meanings.

The OIDF Financial-grade API (FAPI) security profile specifies security requirements for high risk API resources protected by the OAuth 2.0 Authorization Framework that consists of RFC6749, RFC6750, RFC7636, and other specifications.
There are different levels of risks associated with access to these APIs. For example, read and write access to a bank API has a higher financial risk than read-only access. As such, the security profiles of the authorization framework protecting these APIs are also different.
This profile describes security provisions for the server and client that are appropriate for Financial-grade APIs by defining the measures to mitigate:
This profile does not support public clients.
The following ways are specified to protect against modifications of authorization responses: Implementations can leverage OpenID Connect's Hybrid Flow that returns an ID Token in the authorization response or they can utilize the JWT Secured Authorization Response Mode for OAuth 2.0 (JARM) that returns and protects all authorization response parameters in a JWT.
| TOC |
While the name ID Token (as used in the OpenID Connect Hybrid Flow) suggests that it is something that provides the identity of the resource owner (subject), it is not necessarily so. While it does identify the authorization server by including the issuer identifier, it is perfectly fine to have an ephemeral subject identifier. In this case, the ID Token acts as a detached signature of the issuer to the authorization response and it was an explicit design decision of OpenID Connect Core to make the ID Token act as a detached signature.
This document leverages this fact and protects the authorization response by including the hash of all of the unprotected response parameters, e.g. code and state, in the ID Token.
While the hash of the code is defined in OIDC, the hash of the state is not defined. Thus this document defines it as follows.
s_hash
State hash value. Its value is the base64url encoding of the left-most half of the hash of the octets of the ASCII representation of the state value, where the hash algorithm used is the hash algorithm used in the alg header parameter of the ID Token's JOSE header. For instance, if the alg is HS512, hash the state value with SHA-512, then take the left-most 256 bits and base64url encode them. The s_hash value is a case sensitive string.
| TOC |
An authorization server may protect authorization responses to clients using the "JWT Secured Authorization Response Mode" JARM.
JARM allows a client to request that an authorization server encodes the authorization response (of any response type) in a JWT. It is an alternative to utilizing ID Tokens as detached signatures for providing financial-grade security on authorization responses and can be used with plain OAuth.
This specification facilitates use of JARM in conjunction with the response type code.
NOTE: JARM can be used to protect OpenID Connect authentication responses. In this case, the OpenID RP would use response type code, response mode jwt and scope openid. This means JARM protects the authentication response (instead of the ID Token) and the ID Token containing End-User Claims is obtained from the token endpoint. This facilitates privacy since no End-User Claims are sent through the front channel. It also provides decoupling of message protection and identity providing since a client (or RP) can basically use JARM to protect all authorization responses and turn on OpenID if needed (e.g. to log the user in).

API resources may contain sensitive data and/or have increased security requirements. In order to fulfill different security needs, FAPI Security Profile 1.0 defines an advanced profile that is beyond the baseline security requirements defined in the Part 1: Baseline document.
As a profile of the OAuth 2.0 Authorization Framework, this document mandates the following for the advanced profile of the FAPI Security Profile 1.0.
| TOC |
The authorization server shall support the provisions specified in clause 5.2.2 of Financial-grade API Security Profile 1.0 - Part 1: Baseline, with the exception that Section 5.2.2-7 (enforcement of RFC7636) is not required.
In addition, the authorization server
NOTE: MTLS is currently the only mechanism for sender-constrained access tokens that has been widely deployed. Future versions of this specification are likely to allow other mechanisms for sender-constrained access tokens.
NOTE: PAR does not present any additional security concerns that necessitated the requirement to use PKCE - the reason PKCE is not required in other cases is merely to be backwards compatible with earlier drafts of this standard.
| TOC |
In addition, if the response_type value code id_token is used, the authorization server
NOTE: The authorization server may return more claims in the ID Token from the token endpoint than in the one from the authorization response

In addition, if the response_type value code is used in conjunction with the response_mode value jwt, the authorization server

As a profile of the OAuth 2.0 Authorization Framework, this specification references the security considerations defined in Section 10 of RFC6749, as well as RFC6819 - OAuth 2.0 Threat Model and Security Considerations, which details various threats and mitigations. The security of OAuth 2.0 has been proven formally - under certain assumptions - in OAUTHSEC. A detailed security analysis of FAPI Security Profile 1.0 can be found in FAPISEC.
| TOC |
There is no way that the client can find out whether the resource access was granted for a bearer or sender-constrained access token. The two differ in the risk profile and the client may want to differentiate them. The protected resources that conform to this document differentiate them. The protected resources that conform to this document shall not accept a bearer access token. They shall only support sender-constrained access tokens via MTLS.
| TOC |
| TOC |
In RFC6749 and RFC6750, the endpoints that the authorization server offers are not tightly bound together. There is no notion of authorization server identifier (issuer identifier) and it is not indicated in the authorization response unless the client uses different redirection URI per authorization server. While it is assumed in the OAuth model, it is not explicitly spelled out and thus many clients use the same redirection URI for different authorization servers exposing an attack surface. Several attacks have been identified and the threats are explained in detail in RFC6819.
| TOC |
In this attack, the client developer is socially engineered into believing that the token endpoint has changed to the URL that is controlled by the attacker. As a result, the client sends the code and the client secret to the attacker, which will be replayed subsequently.
When the FAPI Security Profile 1.0 client uses MTLS, the client's secret (the private key corresponding to its TLS certificate) is not exposed to the attacker, which therefore cannot authenticate towards the token endpoint of the authorization server.
| TOC |
In this attack, the client has registered multiple IdPs and one of them is a rogue IdP that returns the same client_id that belongs to one of the honest IdPs. When a user clicks on a malicious link or visits a compromised site, an authorization request is sent to the rogue IdP. The rogue IdP then redirects the client to the honest IdP that has the same client_id. If the user is already logged on at the honest IdP, then the authentication may be skipped and a code is generated and returned to the client. Since the client was interacting with the rogue IdP, the code is sent to the rogue IdP's token endpoint. At the point, the attacker has a valid code that can be exchanged for an access token at the honest IdP. See OAUTHSEC for a detailed description of the attack.
This attack is mitigated by the use of OpenID Connect Hybrid Flow in which the honest IdP's issuer identifier is included as the value of iss or JARM where the iss included in the response JWT. On receiving the authorization response, the client compares the iss value from the response with the issuer URL of the IdP it sent the authorization request to (the rogue IdP). The client detects the conflicting issuer values and aborts the transaction.
| TOC |
| TOC |
Various mechanisms in this specification aim at preventing access token phishing, e.g., the requirement of exactly matching redirect URIs and the restriction on response types that do not return access tokens in the front channel. As a second layer of defense, FAPI Security Profile 1.0 Advanced clients use MTLS meaning the access token is bound to the client's TLS certificate. Even if an access token is phished, it cannot be used by the attacker. An attacker could try to trick a client under his control to make use of the access token as described in [FAPISEC] ("Cuckoo's Token Attack" and "Access Token Injection with ID Token Replay"), but these attacks additionally require a rogue AS or misconfigured token endpoint.
| TOC |
| TOC |
In RFC6749 the authorization request and responses are not integrity protected. Thus, an attacker can modify them.
| TOC |
In RFC6749, the authorization request is sent as a query parameter. Although RFC6749 mandates the use of TLS, the TLS is terminated in the browser and thus not protected within the browser; as a result an attacker can tamper the authorization request and insert any parameter values.
The use of a request object or request_uri in the authorization request will prevent tampering with the request parameters.
The IdP confusion attack reported in SoK: Single Sign-On Security – An Evaluation of OpenID Connect is an example of this kind of attack.
| TOC |
This attack occurs when the victim and attacker use the same relying party client. The attacker is somehow able to capture the authorization code and state from the victim's authorization response and uses them in his own authorization response.
This can be mitigated by using OpenID Connect Hybrid Flow where the c_hash, at_hash, and s_hash can be used to verify the validity of the authorization code, access token, and state parameters. It can also be mitigated using JARM by verifying the integrity of the authorization response JWT.
The server can verify that the state is the same as what was stored in the browser session at the time of the authorization request.
| TOC |
As confidential information is being exchanged, all interactions shall be encrypted with TLS (HTTPS).
Section 7.1 of Financial-grade API Security Profile 1.0 - Part 1: Baseline shall apply, with the following additional requirements:
| TOC |
For JWS, both clients and authorization servers
| TOC |
For JWE, both clients and authorization servers
| TOC |
To achieve the full security benefits, it is important the implementation of this specification, and the underlying OpenID Connect and OAuth specifications, are both complete and correct.
The OpenID Foundation provides tools that can be used to confirm that an implementation is correct:
https://openid.net/certification/
The OpenID Foundation maintains a list of certified implementations:
https://openid.net/developers/certified/
Deployments that use this specification should use a certified implementation.
| TOC |
An attacker could prepare an authorization request URL and trick a victim into authorizing access to the requested resources, e.g. by sending the URL via e-Mail or utilizing it on a fake site.
OAuth 2.0 prevents this kind of attack since the process for obtaining the access token (code exchange, CSRF protection etc.) is designed in a way that the attacker will be unable to obtain and use the token as long as it does not control the victim's browser.
However, if the API allows execution of any privileged action in the course of the authorization process before the access token is issued, these controls are rendered ineffective. Implementers of this specification therefore shall ensure any action is executed using the access token issued by the authorization process.
For example, payments shall not be executed in the authorization process but after the Client has exchanged the authorization code for a token and sent an "execute payment" request with the access token to a protected endpoint.
| TOC |
This profile requires both Clients and Authorization Servers to verify payloads with keys from the other party. The AS verifies request objects and private_key_jwt assertions. The Client verifies ID Tokens and authorization response JWTs. For AS's this profile strongly recommends the use of JWKS URI endpoints to distribute public keys. For Clients this profile recommends either the use of JWKS URI endpoints or the use of the jwks parameter in combination with RFC7591 and RFC7592.
The definition of the AS jwks_uri can be found in RFC8414, while the definition of the Client jwks_uri can be found in RFC7591.

| TOC |
The use of MTLS for client authentication and sender constraining access tokens brings significant security benefits over the use of shared secrets. However in some deployments the certificates used for MTLS are issued by a Certificate Authority at an organization level rather than a client level. In such situations it may be common for an organization with multiple clients to use the same certificates (or certificates with the same DN) across clients. Implementers should be aware that such sharing means that a compromise of any one client, would result in a compromise of all clients sharing the same key.
| TOC |
JWK sets should not contain multiple keys with the same kid. However, to increase interoperability when there are multiple keys with the same kid, the verifier shall consider other JWK attributes, such as kty, use, alg, etc., when selecting the verification key for the particular JWS message. For example, the following algorithm could be used in selecting which key to use to verify a message signature:

There are many factors to be considered in terms of privacy when implementing this document. However, since this document is a profile of OAuth and OpenID Connect, all of them are generic and applies to OAuth or OpenID Connect and not specific to this document. Implementers are advised to perform a thorough privacy impact assessment and manage identified risks appropriately.
NOTE: Implementers can consult documents like ISO29100 and [ISO29134] for this purpose.
Privacy threats to OAuth and OpenID Connect implementations include the following:
These can be mitigated by choosing appropriate options in OAuth or OpenID, or by introducing some operational rules. For example, "Attacker observing personal data in authorization request" can be mitigated by either using authorization request by reference using request_uri or by encrypting the request object. Similarly, "Attacker observing personal data in authorization endpoint response" can be mitigated by encrypting the ID Token or JARM response.
