Hi All, I forgot the Pulumi PULUMI_CONFIG_PASSPHRASE after creating the stack, is there a way to reset the Pulumi phase phase or to delete the stack without Impact of Resources?

You can do this via state editing. Export the stack json file and remove all the information about the secret provider and any secret values. I've looked at adding a "--discard" option to change-secrets-provider but its not a quick change to get in.
