To log into Classic, go to app.consigncloud.com. Here, input your email and password. If this is your first time signing into Classic from Next-Gen, you will need to 'reset' your password. You can reset it to the same password; it's just a quirk of how Next-Gen and Classic interface.
NOTE: If you are a Next-Gen user logging into Classic, make sure you don't have any users with passwords before you log in.
Once you are logged in, you should see a dashboard that looks like the screenshot below.
NOTE: Our Classic platform is being phased out slowly. We don't recommend Classic for your main use if you are a new user.
