When logging in to BuyMaterials you will be sent a one-time code via email to login. This avoids holding passwords and thus is more secure. You should have first been presented with this option (either logging in, OR registering for the first time).

once filled in you should see the following screen a code be sent to your email.

If you have not received the code, do press "resend" this will take up to 60 seconds to be sent to your inbox. If after 5 minutes you have not received it, and it is not in your junk items or deleted items, the likely cause will be your email provider/IT provider have blocked the domain "kinde.com" which is our authentication provider. You should contact them to ensure you are received emails from "kinde.com"
