# Attest Session

> Attest Session using the Stytch React SDK

Wraps the [Attest](/api-reference/consumer/api/sessions/attest-session) Session endpoint and gets a Stytch session from a trusted JWT.

## Parameters

<ParamField body="profile_id" type="string" required>
  The ID of the trusted auth token profile to use for attestation.
</ParamField>

<ParamField body="token" type="string" required>
  The token to authenticate.
</ParamField>

<ParamField body="session_duration_minutes" type="int">
  Set the session lifetime to be this many minutes from now. This will return both an opaque `session_token` and `session_jwt` for this session, which will automatically be stored either in the browser cookies if you're using our JavaScript SDK, or in the iOS Keychain/ Android SharedPreferences if you're using one of our mobile SDKs. The `session_jwt` will have a fixed lifetime of five minutes regardless of the underlying session duration, and will be automatically refreshed by the SDK in the background over time. This value must be a minimum of 5 and may not exceed the maximum session duration minutes value set in the [Frontend SDK page](https://stytch.com/dashboard/sdk-configuration) of the Stytch Dashboard. A successful authentication will continue to extend the session this many minutes.
</ParamField>

<ParamField body="session_token" type="string">
  An opaque session token.
</ParamField>

<ParamField body="session_jwt" type="string">
  A JSON Web Token that contains standard claims about the user as well as information about the Stytch session.
</ParamField>
