Social recovery wallets usually use an m of n system where you don't need all keys to recover your wallet but a subset. For example, 9 total keys and any 5 needed to recover your wallet.

Let's say you give a key to a business and that business gets hacked. That's fine because a single key can't steal your wallet and you have 8 keys left. You can even invalidate the keys and generate 9 new ones.
