Not OP commenter but I personally would recommend using pass (https://passwordstore.org), I’m a little paranoid about all this fuzz, plus did you see the news in HN a few months ago about a password manager web browser extension having an exploitable vulnerability? Not sure if it was lastpass but I’ll try to search for it…

Edit: I found an old post from about 5 years ago on a vulnerability in LastPass’s extension [0]
