How does SSO work on different browsers?

Hi Everyone,

I’m a bit new with Auth0 and one have SSO login questions, I have Single Page App A and Single Page App B, I login App A, with user credentials using Chrome browser. When I use App B in chrome, I am automatically logged in because of SSO.

Both apps are open in Chrome, when I open app A in firefox, it requires me to login again?
It does not detect that I am already logged in by Auth0?

Thank you for your help in Advance.


Hi @msuguitan

SSO is based on a session, and sessions are stored in cookies.
Browsers don’t share cookies, so you cannot do SSO between them.
