What happens if you put $1 million dollars in the bank?

I'm curious, if I were to deposit a million dollars into a bank account, what kind of consequences would I face? Would I earn interest on that amount? Are there any restrictions or fees associated with such a large deposit? Would my money be insured in case of any unforeseen circumstances? Additionally, how would this deposit affect my credit score or financial standing? I'm eager to understand the implications of such a significant financial decision.
