Hi,
I'm having an issue - sign in and up doesn't work in browser Incognito mode

i'm getting 401. it works fine in the regular browser mode

whats the sameSite setting of the access token cookie?

you sohuld consider switching to header based auth

or then changing the api domain to be a sub domain of the website domain so that supertokens can set sameSite to lax, and then it should work

if i change the api to be a sub domain will it work automatically? or do I need to change something with Supertokens?

You will have to change the apiDomain config on the frontend and backend. Also, existing users that have logged in will be logged out
