To activate Two-Factor Authentication, you will need to have the ArtStation app installed on your mobile device. If you don't already have it installed, please download and install it on iOS or Android.
From the ArtStation App on iOS or Android, go to Two-Factor Auth from your Settings and enable Two-Factor Auth.
To complete the set up, you will need to confirm via an email that will be sent to you. Please check your spam folder as it may end up in there. Once enabled, you can confirm or deny any log-in requests from the Two Factor Auth Requests page located at the top of your mobile menu bar.
You will have the ability to set a device as trusted so you won’t have to complete 2FA every time.
You’ll be asked to complete 2FA whenever there’s a new sign in or if there is a request to delete your account. Even if someone accesses your account from a trusted device, they won’t be able to erase it without passing a second Two Factor Authentication.
You can view your authorized devices on the website by going to your Settings -> Two-Factor Auth.
