Can our organization require two-factor authentication?

Yes. Organization admins can require all of their users to have two-factor authentication configured. Note that before setting this to the whole organization, you will need to enable 2FA on your own account from the Profile page. 

1. Login at https://app.valohai.com
2. Navigate to Hi, <name> (the top-right menu) > Manage <organization>.
3. Go to Settings under the organization controls
4. Enable "Two-Factor Authentication" and save your changes.

Users will have to set their MFA under their project settings: https://app.valohai.com/auth/
