# Online Auth

tokenproof Online Authentication enables website and application owners to easily integrate tokenproof token gates for seamless proof of ownership. 

Using a few simple lines of code, Verifiers can display a button or widget labeled "Authenticate with tokenproof", which users can select to begin the authentication flow.

Online Auth will refer to a token gate that has been defined using the [tokenproof Console](/documentation/tokenproof-apps/portal.md) and enables users to authenticate past token gates using their tokenproof Mobile App. 

Access is available to all users with an active tokenproof account.
