Suppliers in mainland China can sign in to the supplier portal and their assessments. The code is verified and the session issued entirely by Tappr, so the login completes behind the Great Firewall.
Error messages are distinct: “Invalid magic code” appears only when the code is actually wrong or expired, and anything else shows a general error.
Sessions last 12 hours, or 35 minutes of inactivity, and Log Out ends the session on the server immediately. An expired session shows a clear message on the login screen.
This covers both the supplier portal and assessments on brand subdomains. Every supplier signed in when this deployed enters a new code once; anyone with the page already open should reload before logging in.
