+- If you already have an account, you'll be prompted for your password and then you'll be logged in.
+- If you don't have an account, you'll be asked to enter a password or select a federated sign in option like Google, Discord, Apple, or Facebook.
+- You will then be asked for a 6 digit confirmation code that is sent to your email.
+- Next you will be asked if you want to receive emails. Click "Submit" to proceed.
