Privacy mode is now enabled by default. This feature exists for your wallet's privacy, and requires a site to request access to view your account address.
Your address will only be exposed when you approve it, via a Connect Request screen like this:
There are still some legacy dapps that have not yet updated to properly interact with privacy mode properly. If a user still wants to interact with this type of legacy dapp, they will need to add the site to Connections.
How to allow a legacy site to view your account address:
- Select the circular identicon, on the top-right corner of MetaMask
- Click Settings
- Click Connections
- Add the site address
- Click Connect
