The developers of MetaMask have recently released an update that eliminates the automatic merging of all accounts when a non-custodial wallet interacts with dApps.
With this update, accounts now remain separate in different browser tabs, allowing users to maintain multiple accounts. For example, one account can be used as a public account associated with ENS, while another account can be reserved for private DeFi activity.
The update also provides options to limit data sent to third-party services and change the RPC provider from the default Infura.
This update caused some concern among the community regarding their privacy and the increased risk of being identified by law enforcement.
In response, on December 6, the company announced that it will reduce the data retention period for IP identifiers and wallet addresses to seven days.
