In the meantime, you have essentially two options:
- Recommended approach: Enable 2FA on your primary Ring account, and then add a secondary account with access to your devices; this secondary account will be just for RingForIndigo to use, so give it a ridiculously complex, unique password that you don't use anywhere else.
- Live without 2FA and connect to Ring using your primary account in the RingForIndigo plugin
A potential downside to the first option is a limit on which devices you can access in RingForIndigo - specifically, Chime devices won't be accessible by the plugin.
