What guarantees do we have when verifying the sender's identity (in SmartPy)?

Question

When we check the address that called the current entry point e.g. in SmartPy:
sp.verify(self.data.authorizedAddr == sp.sender)

What guarantees do we have? For example, is it possible for someone else to have called the entry point?

You are guaranteed (if the crypto behind Tezos is not broken) that the person who signed the transaction knew the corresponding private key (in case of an implicit account) so, for all reasonable purposes, you should be good.
