How does a physical token work?
A hard token allows you to access software and verify your identity with a physical device rather than relying on authentication codes or passwords, but still uses multiple factors in authorizing access to software.

How are tokens generated?
How do tokens work? In many cases, tokens are created via dongles or key fobs that generate a new authentication token every 60 seconds in accordance with a known algorithm. Due to the power these hardware devices hold, users are required to keep them safe at all times to ensure they don’t fall into the wrong hands.
Which type of authentication does a hardware token provide?
Hardware tokens typically make use of One-Time Passwords (OTPs), or Time-Based One-Time Passwords (TOTPs), for two-factor authentication (2FA) or multi-factor authentication (MFA). The numbers are usually six-digit codes that expire every 30 seconds.

What is a token in cyber security?
A security token is a physical or digital device that provides two-factor authentication (2FA) for a user to prove their identity in a login process. It is typically used as a form of identification for physical access or as a method of computer system access.
How does Bearer Token authentication work?
How bearer token works? The Bearer Token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for you a Token. Bearer Tokens are the predominant type of access token used with OAuth 2.0.
