What is the difference between `ethers.getSigners()` and `provider.getSigners()`?

Question

I recently encountered both of these and I'm not able to find the difference between them. Are these the same or do they have some differnces?

Answer 1

Basic difference among these two is basically that ethers.getSigners() returns Signer objects for accounts managed by ethers, while provider.getSigners() returns Signer objects for all accounts available on the connected Ethereum node
