# Refresh the session

Use the `refreshSession` method to re-authorize the current session without asking the user to sign in again. It returns a `CompletableFuture<Web3AuthResponse>` with the refreshed session data.

If re-authorization fails, the SDK clears the stored Auth tokens and the in-memory session, and the future completes exceptionally. Prompt the user to sign in again in that case.

## Usage

```kotlin
web3Auth.refreshSession().whenComplete { response, error ->
    if (error == null) {
        // Session refreshed
        val privateKey = web3Auth.getPrivateKey()
    } else {
        // Session could not be refreshed. Show the sign-in screen.
        Log.d("MainActivity_Web3Auth", error.message ?: "Unable to refresh session")
    }
}

```

note

`enableMFA()` and `manageMFA()` call `refreshSession()` internally before opening the MFA flow, so you don't need to call it yourself before those methods.
