If you need to make a credential invalid you can revoke it.
{% hint style="warning" %} To make a credential revocable, you need to select Credential Revocation when issuing credentials. If the revocation was not selected upon creation the credential can never be revoked and will always be verifiable. {% endhint %}
Select Credentials, the credential(s) you want to revoke to make it invalid, and select Revoke. You can revoke one credential at a time.
