Use of OST Platform requires: 

1. A specific business email address to be whitelisted (e.g. email@companyname.com). Generic domains such as @gmail or @yahoo cannot be used.

2. An authenticator app like Google Authenticator for setting up 2FA

3. MetaMask installed on the Chrome Browser, so users can provide an address to receive an initial allotment of OST-Test for use in the sandbox. We also highly recommend using a Hardware Wallet linked to your MetaMask account when moving to the production environment to provide another layer of security for your Brand Tokens.
