# Guide to Using the MetaMask In-app Browser on Mobile

Mobile device users are required to use the MetaMask in-app browser in order to connect to their wallet to the [Affyn marketplace](https://marketplace.affyn.com/) website. MetaMask **will not work** with other browsers such as Chrome or Safari on a mobile device.
