# Login SmashFi allows easy and quick registration and login by using your own account with completed KYC after joining a global exchange. There is no separate registration process required, and after the initial linkage, login is possible through the oAuth authentication method of each exchange. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
