Update
We are currently investigating an issue causing login failures for some users attempting to authenticate to the Supabase dashboard via SSO or email/password login flows.
Affected users may see an error similar to: “captcha protection: request disallowed (sitekey-secret-mismatch)”
Currently logged-in users are not affected, and GitHub authentication continues to operate normally.
We will continue to provide updates as more information becomes available.
