Abstract: A multi-signature method for minting and verifying NFTs for use as a login key to access private content. A user buys an NFT that corresponds to particular private content, and that NFT is stored in the user's wallet. When the user wants to access the private content the method parses all the NFTs stored in the user's wallet to find an NFT that corresponds to the private content, and if there is a match, then the user is granted access to that particular private content. The process of minting, buying, and comparing the NFT for use as a login key for access to private content on a website is made possible by a facilitator that earns a fee for every NFT login key created.
