The Internet is behind a locked door

Units in Intro to Web Design are for people taking the course. Getting in takes a link or a key — signing in on its own doesn't do it.

1 Sign in

With your school Google account. This is how your work reaches the gradebook — it doesn't open the unit by itself.

2 Get in

Open the class link your teacher posted — that's the usual way, and it enrols you on the spot. Or paste an access key if you were handed one.

A key unlocks this browser and keeps your progress here; signing in keeps it with you across devices. Either way the key itself is only ever checked as a hash. Manage all of this on your account, read what signing in stores, or go back to Intro to Web Design.
