#MultiversX has introduced #Guardians , an on-chain two-factor authentication (2FA) feature for wallet security.

The guardian service requires users to create a guardian address to provide 2FA-controlled signatures. Part of the sign-up process sees the wallet prompt the user to finalize the registration by issuing a transaction to the MultiversX network, which will set the service-generated address as a guardian for their account.

After an account becomes guarded on-chain, transactions issued by the user require both the user’s and the guardian’s signatures. The guardian service will provide a valid guardian signature for the user transaction whenever a user with a guarded account sends a transaction from their wallet and provides a valid 2FA code.
