Mill downtime tracker. Managers use their existing Supabase login. Saw names are not logins.
Sign in with an existing mill manager account. This page does not create accounts or send email.
Authorization is mill_downtime.managers. A Supabase login that is not on that list stays on this gate.
Google may ask which account to use the first time, or when this browser has more than one Google session. After that, this browser keeps the Supabase session and refreshes it. That is not a promise that Google will skip the account choice.
