Subject: [PATCH] Fix: Numeric bypass code defaults to integer type

When adding a numeric only bypass code into config.yml, it is treated as an integer which causes validation to fail. A workaround is to surround the parameter with double quotes but many users may not be aware of this. This fix will explicitly convert it to a string.
