# Supabase secret key (`supabase_secret_key`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Secret API key of a Supabase project, which bypasses row level security and must stay on the server. Supabase documents that secret keys start with sb_secret_ and are short strings, not JWTs; the legacy service_role key is a JWT and is the datatype jwt. The vendor does not document the length or the characters after the prefix; the regexp accepts letters and digits.
