This is a domain for centralized services across the entire Stack Exchange network.
In addition to site enumeration for the StackExchange API, StackAuth also serves as the storage domain for our global authentication scheme.
Due to the unreliability of third-party cookies in modern browsers, our scheme uses HTML 5's localStorage to store login credentials under the StackAuth domain...
- I'm pretty sure that the API last used stackauth.com with version 1.1 (Deprecated in 2012).
- Although I remain logged-in to many Stack Exchange sites, plus the API, plus chat, plus SEDE; when I visit https://stackauth.com/, it shows nothing stored in
Is stackauth.com still in use?
If so, when/how? If not, when did it stop?
PS: I use
openid.stackexchange.com to authenticate on the SE network.
