Use a password manager and sufficiently high entropy passwords and you are fine for now. You can't brute force them and because you can't remember them, you won't be typing them manually or do any of the other things that make passwords a problem.
Bio-metrics are convenient though. I use them with my password manager. For things where it matters, use multi factor authentication. Long term, multi will have to be more than 2. The more factors, the harder it is to break through. For example, I use a separate tool to store my 2FA secrets than my password manager (which can do this). That's almost (not quite) an extra factor. You might call it 2.5FA
