SecurID

SecurID is a family of two-factor authentication solutions developed by RSA Security that provides time-based one-time passwords used to verify a user’s identity when accessing corporate networks and applications. In a typical setup, a user possesses a token that generates a six- to eight-digit code, refreshed every 60 seconds. The code, entered with a password, is validated by an authentication server against the token’s seed value and the current time. The exact algorithm is proprietary, and there are variations including event-based tokens and push-based authentication.

The SecurID portfolio includes hardware tokens (key fobs and smart cards), software tokens for mobile devices or computers, and cloud-based or on-premises services known as RSA SecurID Access. These tokens can secure access to VPNs, SSH endpoints, web portals, and cloud applications, often in combination with single sign-on and adaptive risk-based authentication.

Ownership and history: RSA Security was acquired by EMC in 2006; Dell Technologies later acquired EMC in 2016, placing RSA Security within Dell Technologies. The SecurID product line has continued to evolve under the RSA Security banner, with RSA SecurID Access representing an expanded identity and access management solution beyond traditional OTP tokens.
