# Login with Web3

To provide all functionalities users need also log in using web3 signature transaction. Login will happen automatically after scanning QR code. While the application is waiting for the user to login SDK will display a popup that allows the player to disconnect the wallet. That window will always appear whenever the user wallet is connected but not logged in.

Now the player has to open it’s wallet manually in order to sign a transaction message. On the user wallet, transaction information will be displayed and requested to sign the login transaction. After clicking on the **Sign** button the player will be signed into Your game.
