# SignUp

The .NET SDK for SurrealDB enables simple and advanced querying of a remote or embedded database.

Signs up to a specific authentication scope / access method.

```csharp title="Method Syntax"
await db.SignUp(credentials)
```

<table>

        </tr>
        <tr>
            <td colspan="2" scope="row" data-label="Arguments">
                <code>cancellationToken</code>
                <label label="optional" />
            </td>
            <td colspan="2" scope="row" data-label="Description">
                The cancellationToken enables graceful cancellation of asynchronous operations.
            </td>
        </tr>
    </tbody>
</table>

### Example usage

```csharp
// With Record Access
var authParams = new AuthParams
{
    Namespace = "main",
    Database = "main",
    Access = "user",
	// Also pass any properties required by the access definition
    Email = "info@surrealdb.com",
    Password = "123456"
};

Jwt jwt = await db.SignUp(authParams);

public class AuthParams : ScopeAuth
{
	public string? Username { get; set; }
	public string? Email { get; set; }
	public string? Password { get; set; }
}
```

You can invalidate the authentication for the current connection using the [`Invalidate()` method](/docs/reference/dotnet/methods/invalidate.md).
