Revoking A Trello Token
Third-party applications can be granted access to your Trello account via an authorization flow. When you grant access, Trello gives the third-party develop a token that can be used to make requests to Trello on your behalf.
Occasionally, you may need to revoke that token's access to your account. Follow the steps below to revoke a token:
1. Visit Your Account Settings Page: You can quickly navigate your account settings page by logging into Trello and visiting: https://trello.com/my/account. You can also get to your account settings page by clicking on your avatar in the Trello app and selecting "Settings" from the dropdown menu.
2. Scroll Down To Applications Section: The Applications section contains a list of all applications you've granted access to. The listing for each application includes its name, when you granted access, the level of access that was granted, and when the grant expires.
3. Click Revoke Button: Finally, to revoke access to the token, you can click on the Revoke button.
