Cryptoauth is meant to bridge the gap between web2.0 and web3.0 by providing web3.0 identity to any web2.0 application that is willing to accept it.
This allows crypto communities use existing software like Discourse, WordPress, Rocket.Chat, Jitsi, etc. to communicate and coordinate with each other using crypto-native identities. No more requiring private email or registering new accounts just to allow people to post messages on a forum.
From the end-users side anyone with compatible Ethereum Wallet. Cryptoauth supports classic wallets like Metamask browser extension, Opera browser built in wallet, or any other wallet exposing their API in the browser, but also WalletConnect and MyEtherWallet link, and mobile wallets with dapp browsers built it like Trust Wallet and Coinbase Wallet.
From developer site anyone who can configure OpenID Connect in existing software can integrate Cryptoauth within couple of minutes. Sometimes this would require adding a plugin or a library but in most cases those are straightforward operations.
So if you want to provide Discourse forum or collaborative WordPress site for owners of your token you can do it easily with Cryptoauth.
Login with Ethereum Wallet
Restrict login to people owning some ERC20/NFT token
Each integration can specify who can pass through token restrictions. For example you could specify that only owners of more than 100 of given ERC20 token can login to your website
Login with Proof Of Humanity
Special case of token restrictions can be used with special-purpose tokens. Proof-Of-Humanity provides ERC20 compatible proxy contract that can be used with Cryptoauth to limit login to only people who passed humanity test at https://www.proofofhumanity.id
Example: https://gov.proofofhumanity.id
Login with NFT Tokens
Work In Progress
This feature will enable you to use your NFT tokens to login to any website accepting NFTs as identity. This will be configured per-integration and developers will be able to define additional restrictions.
