According to the present invention, a method for delegating a login via PKI-based authentication for a login request of a user by using a smart contract and a blockchain database is provided. In the method, when information requesting for delegating the login via an authentication app executed by a user terminal is acquired from a service-providing app, a service-providing server transfers authentication request response information to the service-providing app, and when server challenge request information is acquired after an authentication redirection request of the service-providing app is transferred to the authentication app, the service-providing server transfers server challenge request response information to the authentication app, thereby supporting determination of whether certificates of the server and the app are valid, and if the certificates are valid, the service-providing server transfers an access token to the service-providing app, thereby enabling the service-providing app to use the service, and thus processing the login.
