High-Yield Savings Accounts are something distinct from normal savings accounts. I don’t believe there are any HYSAs being offered that have rates as low as 1%.

You can find many institutions online offering HYSAs. It is definitely pretty common. In personal finance circles it’s very often recommended to put your emergency fund in a HYSA.

And yes, as you noted, HYSAs have different rules than normal savings accounts. Just like how CDs do.
