According to the same researcher, 1Password has no trackers. 1Password does use UserID & DeviceID as identifiers though.

FWIW they do conduct regular security audits and post it at https://support.1password.com/security-assessments/ . The most recent one was done by Cure53 in 2020-Oct [1].

I've been a happy 1Password Family user for a few years now. Very easy to share common account login credentials, important documents etc with the family.
