I would like to buy a device that can be provisioned with a secret seed and then displays a time based authentication token without ever revealing the seed.
As terms like 2FA, TOTP and Authenticator are almost guaranteed to only show up information about mobile-phone-hosted token generators, i am somewhat struggling to find relevant manufacturers.
I have found some devices using the term "oath-TOTP", but the high frequency of "if you lose your seed, just call us" and "you need adobe flash player to order" makes me think i am not quite using the right search terms to find a trustworthy product.
What is that device class called?
