Website authentication outage

Incident Report for Expo

Resolved

Between 3:44 PM and 4:08 PM PDT, existing sessions on expo.dev were treated as invalid, and users were unable to sign back in. During this window, login attempts from the website failed. The issue has been resolved and users can now sign in normally. We're investigating the root cause.
