Warframe is a violent but very popular game. But when you’ve stopped playing, you might of course be considering to close your account. In that case: The only method to remove a Warframe account is by contacting their customer support team. They won’t make a problem of it, as you’ll notice in the screenshots below.
I’ll show you how you can delete your profile in 5 clicks:
1 Go to https://warframe.com/login?destination=zendesk
2 Log in to your account
3 Submit a request
4 Select ‘Account’
5 Send the removal request
ask them to cancel your account and don’t forget to mention your username and email associated with the account.
Your message could be looking like this:
Subject: Request to delete account
Description: Dear customer support of Warframe,
I accidentally created an account on your website and want to close it.
Username: [your username]
Email associated with the account: [your email address]
Thanks in advance for helping me out.
Category: Other account issue
You’ll receive an email, warning you for the consequences of a permanent removal. All you need to do now, is reply on the mail that you’re sure that you want to remove your profile + answer the security questions they ask you in the mail (=identity check). Afterwards, they will close it.
