# Operator authentication

### Happy path flow

Betlink requests the operator for a temporary launch token. Once the token has been obtained, Betlink acquires an access token and a session from Betlink backend by exchanging the launch token. The access token and the session cookie is used to place bets.

### Token refresh flow

When the previously obtained access token/cookie has expired, and when the user tries to place a bet, the whole process of obtaining a new launch token, access token and cookie is repeated and bets are placed as soon as the auth info is refreshed.
