Rookie question on keeping proceeds from sale liquid

[Julia Taylor]

My husband and I sold our investment property and are about to close on selling our primary residence. We have not identified a new primary or investment property to purchase yet. We will have about $1.3M we want to keep liquid so we are ready to purchase when we find the right properties. What is the safest way to store the money and keep it liquid? We have some high-yield savings accounts at an online bank, as well accounts at our local bank where the interest rates are pathetic. I'm not sure I fully understand what FDIC insurance covers, but want to make sure our money is protected from any fraud or cyber incidents while we shop for another house. I may be overthinking this - I've just never had this much cash on hand and it makes me a little nervous!
