### How to Read This Matrix

* **Single Factor Authentication**\
  Users can authenticate without entering a password, using a single secure method such as biometrics, passkeys, or device-based authentication.
* **Multi-Factor Authentication (MFA)**\
  Users authenticate using a combination of factors, such as password + OTP, biometric + PIN, or device + approval.

#### Important Notes

{% hint style="info" %}
Authentication methods are applied as part of configurable authentication journeys.
{% endhint %}

{% hint style="info" %}
Some methods can be used independently for single factor authentication or combined with other login methods for multi-factor authentication.
{% endhint %}

{% hint style="info" %}
PIN and OTP-based methods (including SMS, Email, Voice, app-generated codes, and hardware tokens) are reserved for use as second factors in two-factor (2FA) or multi-factor (MFA) authentication flows.
{% endhint %}

## 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/passwordless-for-web-apps/authentication-matrix.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.
