For you to use Trusona with your Bank website, your Bank would have to deploy Trusona technology for its customers. Similarly, for other organizations like PayPal, they would have to deploy it.

You do have the option to use Trusona with products that doesn't require the need for a company to offer it to you explicitly. It is our 2-factor authentication experience (a.k.a. TOTP) - We have 100+ applications that we support in that 2-factor authentication mode.
