The unlimited approval problem: Token Allowance Checker

Many DApps have the habit of requiring you to approve effectively unlimited amount of tokens – this also means that the DApp (or the person/entity controlling it) can at any time transfer all of your tokens, without requiring any further approval. This tool shows all approvals for your ERC20-compliant tokens, and the option to change the approved amount – or completely zero it.
