User Authentication Technologies

User authentication technologies encompass a variety of products and services implementing a range of authentication methods in place of legacy passwords. Methods are typically classified by the kind of authentication attributes (or factors) that they use, alone or in combination: something known, something held (a token) or something inherent (a biometric characteristic). Authentication may be natively supported in products or services (including other security tools), or provided by discrete software, hardware or cloud-based services.
