Security Token

A physical or digital device used for authentication to secure access to systems.

Understanding:

A security token is a physical or digital authentication device used to verify identity, grant access, and enhance security. Tokens are commonly used for multi-factor authentication (MFA) and secure transactions.

Common Applications and Use Cases:

Hardware Tokens (e.g., YubiKey, RSA SecurID) – Used for MFA in enterprises.
Software Tokens (e.g., Google Authenticator, Authy) – Generates time-based OTPs.
Cryptographic Security Tokens – Used in blockchain authentication and digital signatures.

Best Practices and Security Considerations:

Use Strong Cryptographic Algorithms – Prevents token cloning or forgery.
Enable Multi-Factor Authentication (MFA) – Reduces risk of credential compromise.
Secure Token Storage – Protects against theft and unauthorized access.
