Hi, welcome to Spider ID. 🙂 This is a False Black Widow, Steatoda grossa.

Their venom is similar to but considerably less toxic to people than a Black Widow’s (Latrodectus). They’re usually not anything to worry over, I wouldn’t want one in my bed though. You can reduce the number of spiders you find in your home by sealing cracks around windows, floors, doors, foundation etc., vacuum everywhere and empty the canister outside.
