Changelog: 04.08.2026 v 1.0.1 - To improve security, the contents of the "secret" field are now hidden by default. This helps prevent accidental leaks when sharing your screen or when someone is looking over your shoulder. You can still view or copy the contents by clicking inside the field. - A minor UI improvement: when you click inside the "secret" field, its contents are automatically highlighted. This makes it easier to copy the value or delete/replace it.
