***

### Email verification

Verify ownership of an email address via magic link.

**What it does** — Sends a verification link to the specified email address. The user clicks the link to confirm ownership, after which the email is added to their identity profile as a verified attribute.

**When to use it** — Adding a verified email as a personal attribute in the user's identity profile.

**Key details**

* Magic link-based verification
* Resend option if the link is not received
* Multiple email addresses can be enrolled

***

### Phone number verification

Verify ownership of a mobile phone number via SMS.

**What it does** — Sends a verification SMS to the user's phone using their active SIM. Once verified, the number is added to the identity profile as a confirmed attribute.

**When to use it** — Adding a verified phone number as a personal attribute, supporting SIM binding workflows.

**Key details**

* SIM-based verification
* Supports dual-SIM devices
* Adds a green checkmark indicator on success

***

### Driver's License enrollment

Capture and verify a government-issued driver's license.

**What it does** — Scans the front and back of a driver's license, captures a confirmation selfie, and verifies authenticity through document analysis. Extracted data fields are added to the identity wallet.

**When to use it** — Identity proofing flows that require a government-issued ID, KYC workflows, and high-assurance onboarding.

**Key details**

* Front and back image capture
* Selfie liveness confirmation
* Automated authenticity verification
* Extracted fields stored in identity wallet

***

### Passport enrollment

Capture and verify a passport, with optional RFID-based authenticity check.

**What it does** — Scans the photo page and back of a passport, captures a confirmation selfie, and verifies the document. RFID-enabled passports can be additionally verified via NFC for cryptographic chip authentication.

**When to use it** — International identity proofing, regulated industries requiring high-assurance documents, KYC for cross-border services.

**Key details**

* Front, back, and selfie capture flow
* Optional RFID/NFC chip verification
* Extracted MRZ data stored in wallet
* Automated tamper detection

***

### Social Security Number enrollment

Capture and store a verified Social Security Number.

**What it does** — Accepts the user's SSN with a declaration of accuracy. The SSN is bound to the user's already-verified biometric identity, providing an additional layer of personal data for high-assurance flows.

**When to use it** — US-based KYC, financial services onboarding, and government identity proofing requiring SSN verification.

**Key details**

* Requires LiveID enrollment as a prerequisite
* Requires Driver's License or Passport enrollment as a prerequisite
* Declaration consent required before submission

{% hint style="info" %}
**Prerequisites for SSN enrollment.** A LiveID and at least one government-issued ID document (Driver's License or Passport) must be enrolled first. This ensures the SSN is bound to a verified biometric identity.
{% endhint %}

### Identity Assurance Level (IAL) scoring

Quantify the strength of a user's verified identity.

**What it does** — Calculates a baseline score based on the biometrics, documents, and personal attributes the user has enrolled. The score is visible in the user's profile and grows as more identity assets are added.

**When to use it** — Risk-based authentication, regulatory compliance reporting, and conditional access policies that require a specific assurance level.

**Key details**

* Aligned with NIST 800-63 IAL standards
* Visible to the user in their profile
* Used by relying parties to make access decisions
* Increases as more identity assets are enrolled

### Verification asset matrix

| Asset            | Required prerequisite   | Verification method                    | Stored in wallet |
| ---------------- | ----------------------- | -------------------------------------- | ---------------- |
| Email            | None                    | Magic link                             | ✅                |
| Phone number     | None                    | SMS with SIM binding                   | ✅                |
| Driver's License | None                    | Document scan + selfie                 | ✅                |
| Passport         | None                    | Document scan + selfie + optional RFID | ✅                |
| SSN              | LiveID + DL or Passport | Self-declared, identity-bound          | ✅                |
| LiveID           | Touch ID / Face ID      | Real-time selfie capture               | ✅                |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

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/authentication/1kosmos-mobile-application/application-capabilities/identity-verification.md?ask=<question>&goal=<endgoal>
```

`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.
