If you are a Shopify user, you do not have any password setup. You will just need to log in from your Shopify Admin account >> App >> Vidjet. This will automatically log you into your account where you will be able to create your campaigns and check analytics.
If you are NOT a Shopify user and need to reset your password, then just reach out to us directly (contact@vidjet.io) from the email you signed up with or send us a chat, and our team will be happy to help.
