It is my understanding that Metamask brings a convenient way for the user to interact with DApps by storing their wallets and by providing an interface that gives the user control of what the DApp is doing. Is this correct?
If the user does not mind at all inserting the wallet address and password, and they fully trust the app, is there any reason to use Metamask? Web3.js allows doing everything that Metamask does in the browser as well, right?
