Chrome on iOS integrates into the operating system as an alternative password manager, which for example allows users to access their (e.g. Netflix) password when logging into (non-browser) apps.
Unfortunately, Brave is not listed as a password AutoFill provider (“Allow filling from”).

Would propose that this feature is added for people who don’t use a full password manager like 1password, Bitwarden, etc.
