So far, there is only one way to do this.
This requires one of the text editing software and a bit of knowledge about the JSON file format.
I recommend using professional software to work with this format, such as VS Code, because it also checks the formatting.
First, open the “userfiles” folder.
You can do this from the settings or manually according to this guide.
Then open the “dbs.json” file in a text editor.
The key “phrase” is your password.
You can change it in a text editor, but you only need to do this when the application is not in use.
