Yo, peeps! Let's talk 'bout this whole multi-device login thing. You know, where you can just log in once and access your stuff on all your gadgets? Yeah, that's cool, but tech part? It's like trying to understand quantum physics with a crayon. So, here's my guide to ugly, ugly world of cross-domain cookie login. Let's dive in!

Understanding Ugly Challenge: Cross-Domain Access

So, in world of web apps, we got this thing called cross-domain access. It's like trying to get your neighbor to give you a cookie, but ir door's locked. But fear not, for we have cookies, and cookies can be tricky little things. We can use m to get around se doors and log in everywhere.

Single Sign-On (SSO): The Cookie Strategy

Now, SSO, or Single Sign-On, is like having one key to open all locks. It's magic trick of logging in once and being able to access all your stuff. There are like a billion ways to do it, but let's focus on cookie strategy. You know, like sharing cookies with your friends.

The path is like folder on your computer where cookie gets saved, and domain is like website that can read cookie. It's like having a cookie that only your best friend can eat.，我的看法是...
