Digi-Access™ competes directly with asynchronous number and One-Time Password [OTP] tokens like RSA® SecurID® but this older technology. There have been many improvements since the original SecurID® idea, but the technology is still basically the same. In their favor, tokens are easy for the user to understand (it’s just a more powerful password) but the initial and ongoing costs are expensive. Tokens do provide good two factor authentication, but that’s it.
More and more organizations are moving towards Digital Certificates to solve their authentication issues because they are more flexible and provide additional functions (albeit they may not be needed immediately). If your Storage Type is the Certificate Store within the browser, there are significant cost savings to consider.
