I have 2 applications and I want to automatically login to the other site if im already logged in. I have a parent app with a link to a wordpress app both using auth0 (wp is using the auth0 plugin). I’ve tried setting cookie domain and keep getting a state error. Ive also updated all the allowed origins and callback urls on both applications. The strange thing is that it was working for a minute and now it does not and I cant figure out why. When i run the app locally, it logs me in automatically.

Hi @mliang,

Could you tell us what connections both apps are using? Do they both have the same WordPress social connection? And what do you mean by parent app?

Have a good one,
