About NFT Authenticator

Verify ownership of your NFT to gain access to events and exclusive opportunities using NFT Authenticator; the first 2-Factor Authentication app that works directly with your wallet.
NFTs that are minted on the Ethereum/Polygon network can be verified in seconds.

First, simply connect to your MetaMask® wallet, select your NFT, and present the QR code to a staff member. Then, to authenticate ownership of your digital asset, you’ll be asked to “sign” a random single-use message by simply tapping a button. If you haven’t purchased an NFT yet, you can visit nftauthenticator.io or attentionblock.com for a list of all our supported projects.
