What will _actually_ work today?
1. Never, ever reuse passwords.
2. Use a good, reputable password manager.
3. Use diceware for any passwords you have to remember (such as for your password manager).
4. MFA ALL THE THINGS. Preferably with a security key if available. If passkeys are an option look into them.
5. Don't rotate your passwords or change them unless you know there is a compromise, but subscribe to services to let you know about compromises (haveibeenpwned, etc)
