Did you know that?

If that app turns out to be a scam or rug pull, your financial data is in the hands of scammers.
Another issue is that any app is vulnerable to hacking. The chance that a single app will be hacked is tiny. But if you connect to 100 apps, the chances are 100 times higher!
Therefore, disconnecting the apps you don’t use often is very beneficial. It will protect your privacy and improve security.

Even if you disconnected your Metamask from a website, but gave some smart contracts permissions to move your wallet’s funds, those smart contracts will still be able to do it with their access tokens.

In those services, simply enter your wallet address and press search (on Etherscan you can just connect your wallet by pressing “Connect to Web3”):
