# Revoke a token approval
Take back permission you gave a contract to spend your tokens.
When you approve a token for a dApp, that contract may move your tokens up to the allowed amount, sometimes **Unlimited**. Revoking sets the allowance back to zero. *This is a transaction, it goes through your vault.*
{% stepper %}
{% step %}
### Open Revoke an approval
**Menu → Revoke an approval** (*Cancel a token allowance*). Pick the network and the token.
The revoke screen.
{% endstep %}
{% step %}
### Enter the spender and check the allowance
Paste the **Spender (contract)** address and tap **Check current allowance**. The wallet reads it from the chain: an amount, or **Unlimited**.
The current allowance.
{% endstep %}
{% step %}
### Revoke and sign
Tap **Revoke**. The Vault shows **Revoke token approval** with the **Spender**. Sign, scan back, done.
{% endstep %}
{% endstepper %}
{% hint style="info" %}
Where do I find the spender address? On the site you approved, or on a block explorer's *Token approvals* page for your address.
{% 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://doc.lockerprotocol.com/browser-extension/revoke-an-approval.md?ask=&goal=
```
`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.
