LastPass is shit now.

Firefox is fine if it’s all you use. I use the Apple Passwords app, because I have all Apple stuff (Macs and an iPhone). It works very well.

You can also use BitWarden. That’s free, it’s open source, and it’s highly regarded. It works whether you use iPhone or Android; whether your computer runs macOS, Linux, or Windows.

You don’t need to pay for a password manager. Anyone who says you do has a vested interest in you spending money (it typically directly relates to them making money), and if they can’t respect you enough to be transparent about it, they don’t deserve your money.
