Too Long; Didn't Read
Built-in web browsers have built-in password managers do the job, but not as good as third-party ones. Password managers can point out weak passwords and will even let you know if a database containing your password has been leaked. They also allow you to store things other than password managers such as secure notes that you can encrypt for better security. Some of the best password managers include 1Password, LastPass, Bitwarden, and Dashlane. You can import everything from your web browser to a new password manager.
