The short answer
Open the lab from your partner site while you are signed in there. It signs you in to a lab-only account, separate from an edwartens.com account, so you do not sign in again.
Partner site to lab
1Sign in on edwartens.co.uk
2Open the lab from there
3You are signed in
No second password
Learners on our UK partner site, edwartens.co.uk, can use the 3D Lab without making a second account.
How it works
- Sign in on edwartens.co.uk.
- Open the lab from that site.
- The lab signs you in. Your name and email there are used only to look after you.
What to know
- Your lab account is lab-only. It does not sign you in to edwartens.com, and it cannot receive email from us at a made-up address.
- If you also have an edwartens.com account with the same email, the two stay separate.
- To use the lab again, open it from edwartens.co.uk each time.
If the lab says your sign-in has expired, go back to edwartens.co.uk and open the lab again.
For anything else, write to info@wartens.com.
