Article Forge accounts are meant for individual use. This means that only one person can be logged into an account at a time.
But, Article Forge supports adding multiple user seats to your account so that each user can log into your main account with their own credentials. You can also set permissions for each user seat for added security.
If you are on a 500,000 words/month plan, you can add additional users to your subscription. Each user will have their own login information but will be part of the same subscription and will have access to the same main account.
If you are not on a 500,000 words/month plan, you will need to upgrade your account to add additional user seats.
