Blockchain protocol MultiversX (formerly Elrond) has implemented a new two-factor authentication standard, Guardians, which is now being used as an additional transaction signing measure on the MultiversX blockchain protocol to add additional security to its network. This feature leverages Google Authenticator, Authy, Duo, Microsoft Authenticator, or biometrics to provide a second signature before transactions are processed on-chain.

MultiversX CEO Beniamin Mincu said that the extra security should not come at the expense of user experience, but should aim to reduce the friction of signing transactions.
