# Overview
***
One app for passwordless authentication, identity verification, and verifiable credentials.
***
### Why it exists
Traditional multi-factor authentication (MFA) adds an extra layer of security by checking if you have access to a registered device, like your phone. But it doesn’t fully confirm your identity, it only proves that someone has the device, not who they actually are.
That’s where 1Kosmos App comes in.
The 1Kosmos app is designed to go beyond basic authentication and truly verify who you are. It brings everything together in one place:
* **Passwordless login** – securely sign in using your face or biometrics, no passwords needed
* **Digital identity wallet** – store and share verified identity details safely, only when needed
In short, it doesn’t just check if you have a device, it ensures **you are really you**, making access more secure and seamless.
### What you can do with the app
{% tabs %}
{% tab title="Authentication" %}
**Log in to anything, without a password**
* Approve logins via push notification with one tap
* Scan QR codes for instant cross-device authentication
* Generate offline-capable workstation OTPs
* Authenticate with Touch ID, Face ID, or LiveID liveness detection
{% endtab %}
{% tab title="Verify identity" %}
**Prove who you are to the level required by regulation.**
* Scan government-issued IDs (Driver's License, Passport)
* Confirm liveness with real-time selfie capture (LiveID)
* Verify Social Security Number and contact details
* Achieve NIST IAL2 identity assurance
{% endtab %}
{% tab title="Carry credentials" %}
**Store and share verifiable credentials.**
* Receive credentials from trusted issuers (employers, schools, agencies)
* Share only the attributes a relying party needs (selective disclosure)
* Keep credentials on-device, encrypted and tamper-proof
* Use W3C Verifiable Credential standards for interoperability
{% endtab %}
{% tab title="Recover & migrate" %}
**Move to a new device without a helpdesk ticket.**
* Back up your wallet with a 12-word recovery phrase
* Restore identity documents and credentials on any new device
* Transfer accounts via QR code from your old device
* Retain biometric assurance through device changes
{% endtab %}
{% endtabs %}
### Who it's for
{% stepper %}
{% step %}
**For IT and security leaders**
You need to eliminate password-based attacks, comply with MFA mandates (CISA, PCI-DSS, HIPAA), and reduce credential-related helpdesk costs, without disrupting your users. 1Kosmos delivers phishing-resistant authentication with a user experience employees actually adopt.
{% endstep %}
{% step %}
**For product and growth teams**
You want to reduce signup friction, eliminate password resets, and offer a login experience that feels modern. With QR-code login and biometric authentication, 1Kosmos can take your conversion rate to where it should be.
{% endstep %}
{% step %}
**For compliance and risk teams**
You need to verify customer identity before granting access to regulated services — KYC, AML, healthcare data, financial accounts. 1Kosmos provides NIST IAL2-compliant identity proofing with documented audit trails and standards-based credentials.
{% endstep %}
{% step %}
**For end users**
You want to stop remembering passwords, stop getting locked out, and stop worrying about your data being breached. With 1Kosmos, you log in with your face. Your identity stays on your device. You're in control.
{% endstep %}
{% endstepper %}
### What makes 1Kosmos different
**Identity, not just authentication**
Most authenticator apps only confirm possession of a phone. 1Kosmos verifies the actual person -through documents, biometrics, and liveness detection, and binds that verified identity to every authentication event.
**Privacy by design**
Identity data lives **on your device**, not in 1Kosmos's cloud. Biometrics are processed in the device's secure enclave. Credentials use selective disclosure so users share only what's needed. There's nothing for an attacker to steal at scale.
**Standards-based and decentralized**
Built on **W3C Verifiable Credentials**, **NIST 800-63 IAL2**, and **FIDO2** standards. Credentials are issued, held, and verified using open protocols, not proprietary lock-in. Relying parties can verify credentials cryptographically without phoning home to 1Kosmos.

## 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/editor.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.
