# OAuth Authentication

As of version 4.1 we introduced multiple ways to connect to snowflake. 

1. It is no longer required to configure a ODBC DSN. Only the name of the ODBC driver is needed to connect trough odbc. 
2. We also support connecting through OAuth instead of username/password

## Snowflake OAuth

To connect to snowflake trough OAuth, a [custom client integration](https://docs.snowflake.com/en/user-guide/oauth-custom) in snowflake is needed. The steps needed to set this up are explained in the management console on the add connection screen as shown below.

{% hint style="info" %}
To use the oauth functionality on Windows, please update the odbc driver to the latest version.
{% endhint %}

{% hint style="info" %}
An access token is valid for 10 minutes by default in snowflake. WriteBackExtreme will request a token every 8 minutes in the background.&#x20;
{% endhint %}

{% hint style="warning" %}
Do not create multiple connections with the same integration.
{% 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.infotopics.com/writebackextreme/features/database-connections/snowflake/oauth-authentication.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.
