Always use offline password managers like KeePass or Bitwarden. It's aup to you if you keep all your wallets info together with other stuff or keep a separate db for wallets and another one for other stuff.

Important is to have a strong master password and that db file is stored on an offline USB device that is also encrypted. You can make several copies of that db file (and updated them every time there's a change) and keep them in separate locations.

Do not put a db file named "bitcoin passwords" on your desktop screen or write the master password on a sticker under your keyboard... come on these are stupidities.

An encrypted USB with a strong password and an encrypted db file is a double barrier to reach your personal data.
