Magic Link
A sign-in link sent to a teacher's school email — one click plus a confirmation button.
Teachers sign in by clicking a link emailed to their school address. Confirms the teacher owns the email address before signing in, and lets them personalize the Hub (star resources, save preferences).
How it works
Teacher enters their school email at the Hub.
A one-time sign-in link arrives in their inbox.
They click the link, which opens a confirmation page, and press Continue to sign in — and they're in.
Sessions last 30 days, so teachers don't get bumped out mid-class.
What district IT can do
Two small mail-system tweaks help magic links arrive reliably:
- Allowlist the Modern Classrooms Project sender domain so sign-in emails aren't quarantined.
- Exclude our sign-in domain from URL rewriting. Some mail security tools rewrite links in incoming mail, which can mangle the sign-in link or block it behind a warning page. (Ordinary link scanning is handled — the link opens a confirmation page, and sign-in only completes when the teacher presses the button — but scanners that simulate full page interaction can still invalidate a link.)
If a link doesn't arrive, district mail filtering is almost always the cause. See the runbook.
Links expire after 24 hours and work once
A sign-in link is essentially a password — it can only complete sign-in a single time, and it expires after 24 hours. If a link has been used or expired, the teacher just requests a new one.
