I want to show the login form, not the entrant registration form
This article originally described a V1 widget setting (w_['startwith']="login") that is no longer supported. EntryThingy V2 works differently -- here's what you need to know.
How V2 handles login and registration
In V2, EntryThingy is hosted at app.entrythingy.com and artists access calls through direct links rather than embedded JavaScript widgets. When an artist clicks on a call link and they're not logged in, they'll be prompted to either log in or create an account before they can apply.
If you embed EntryThingy on your website
If you use an iframe to embed EntryThingy on your site, you can link directly to the login page URL instead of the registration page. Simply set the iframe source to your call's login URL.
For most galleries, sharing the call link is enough
In practice, most galleries just share their call link (e.g., https://app.entrythingy.com/your-gallery/your-call). Artists who already have an account will be prompted to log in when they click "Apply." New artists will see the option to register. There's no need to separately direct people to a login form -- EntryThingy handles the flow automatically.
