Fido2: definition: fido2 is an open authentication standard that enables passwordless authentication using public key cryptography. purpose: it aims to eliminate the need for passwords and enhance security by relying on biometrics or physical security keys for authentication.
Openpgp (pretty good privacy): definition: openpgp is an open standard for email encryption that uses asymmetric key pairs to secure communications. purpose: it ensures the confidentiality and authenticity of email messages by encrypting the content and providing a means to verify the sender's identity.
Oath (initiative for open authentication): definition: oath is an organization that develops open standards for strong authentication. purpose: oath standards include algorithms and protocols for the generation of one-time passwords (otp) and other forms of authentication, promoting interoperability and security in authentication mechanisms.
Otp (one-time password): definition: otp is a password that is valid for only one login session or transaction on a computer system or other digital device. purpose: it adds an extra layer of security by requiring a unique password for each login attempt, reducing the risk of unauthorized access.
Fido u2f (universal 2nd factor): definition: fido u2f is the predecessor to fido2, focusing on providing an additional layer of security through the use of physical usb or nfc tokens. purpose: it enhances two-factor authentication by requiring both a password and a physical token for access.
Piv (personal identity verification): definition: piv is a standard for secure and reliable forms of identification, primarily used by u.s. federal agencies. purpose: piv cards often contain cryptographic features for secure access to physical and digital resources, serving as a form of multifactor authentication.
