The three identity assurance levels, as defined in [NIST Special Publication 800-63](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-63-3.pdf), are: | Level | Description | | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | | **IAL1** | No requirement to link the individual to a specific real-life identity. Any information provided by the individual should be treated as self-asserted. | | **IAL2** | Uses digital documents to support the real-world existence of an identity and verifies that the correct person is associated with it. | | **IAL3** | Requires an authorized and trained representative to verify the individual in person. | Users can upgrade their own status to IAL2 in AdminX by using the 1Kosmos web-based identity-proofing flow. Tenant and community administrators can trigger this flow using OpenID Connect (OIDC) ACR claims or SAML. ### Automated Ways to Get to IAL2 1Kosmos follows guidelines from [NIST SP 800-63A](https://pages.nist.gov/800-63-3/sp800-63a.html) for remote identity proofing, attempting to strike a pragmatic balance between availability and convenient access to identity-proofing services and the security of the associated processes. Several combinations of evidence quality are accepted at IAL2: * **One piece of SUPERIOR or STRONG evidence** (depending on the strength of original proof and validation with the issuing source), or * **Two pieces of STRONG evidence**, or * **One piece of STRONG evidence plus two pieces of FAIR evidence** | Type of Evidence | Strength | Notes | | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | US Passport | SUPERIOR | Includes US Passport cards | | Foreign e-Passport | SUPERIOR | | | Personal Identity Verification (PIV) card | SUPERIOR | | | Common Access Card (CAC) | SUPERIOR | | | Personal Identity Verification Interoperable (PIV-I) card | SUPERIOR | | | Transportation Worker Identification Credential (TWIC) | SUPERIOR | | | Permanent Resident Card | SUPERIOR | Issued on or after May 11, 2010 | | Native American Enhanced Tribal Card | SUPERIOR | | | REAL ID cards | STRONG+ | Includes REAL ID driver's licenses and ID cards. REAL ID cards have a star printed in the upper right-hand corner. Card and personal information must be validated with the appropriate DMV or AAMVA. | | Enhanced ID cards | STRONG+ | Includes Enhanced ID driver's licenses and ID cards. Must be validated with the appropriate DMV or AAMVA. | | U.S. Uniformed Services Privilege and Identification Card (U.S. Military ID) | STRONG+ | Includes Uniformed Services Dependent ID Cards. Must be validated with the appropriate military issuing source. | | Permanent Resident Card | STRONG | Issued prior to May 11, 2010 | | Native American Tribal Photo Identification Card | STRONG | | | Driver's License or ID card (REAL ID non-compliant) | STRONG | | | School ID card | FAIR | Includes facial image photograph | | Utility account statement | FAIR | | | Credit/debit card and account statement | FAIR | | | Financial institution account statement | FAIR | | | US Social Security Card | WEAK | | | Original or certified copy of a birth certificate issued by a state, county, municipal authority, or outlying possession of the United States bearing an official seal | WEAK | | 1Kosmos provides journeys that allow users to get to IAL2 depending on the evidence collected from them. ### In This Section * **IAL2 Verification** — Create and manage a one-time IAL2 verification flow. * **One-Time Verification** — The end-to-end one-time identity verification journey. * **Triggering IAL2 Verification Using OAuth 2.0 and OIDC** — Trigger step-up verification with custom scopes and ACR claims. * **Triggering IAL2 Verification Using SAML** — Trigger verification using `RequestedAuthnContext`. * **Identity Wallet Based Verification** — Reuse previously verified identities stored in the user's wallet. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.1kosmos.com/identity-verification/ial2-verification/overview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
