# Generic Sign-Up / Sign-In

Generic Sign-up / Sign-in allows the 3rd party (L1 Org) to handle authentication via Web3Connect, and it does not require the end-user to install Web3Wallet beforehand.

After the authentication is passed, then the 3rd party can use the returned ID-Token to re-use the authentication result in the future.

The difference between ID-Token and THXNET. API Token is, ID-Token is used by the end-users, and THXNET. API Token is used by developers of L1 Org.
