Claim 8:
9. The method of claim 1, wherein the new access token is a first new access token and the new refresh token is a first new refresh token, and wherein the method further comprises:
storing, in a blockchain architecture, a stored blockchain that comprises the initial authorization grant, the public key, the attestation of authenticity of the native application, the refresh token, and the digital signature of the refresh token that are utilized by the authentication server to generate the first new access token and the first new refresh token;
retrieving, from the blockchain architecture, the stored blockchain;
generating, by the authentication server, a second new access token and a second new refresh token by using the initial authorization grant, the public key, the attestation of authenticity of the native application, the refresh token, and the digital signature of the refresh token from the stored blockchain;
comparing, by one or more processors, the first new access token and the first new refresh token to the second new access token and the second new refresh token in order to determine that the first new access token and the first new refresh token match the second new access token and the second new refresh token; and
in response to determining that the first new access token and the first new refresh token match the second new access token and the second new refresh token, authorizing, by one or more processors, the first new access token and the first new refresh token generated by the authorization server to be transmitted from the authorization server to the native application.
