I appreciate what @fourwheelcycle said about keeping the data out of the cloud. I don't think I can set up a system like @fourwheelcycle's. I am interested in learning about 1P's security features, as I consider moving to 1P Families
Thank you very much for getting in touch with us. I have split the thread because the previous thread was a bit old, I hope you don't mind I'll be glad to tell you more about how 1Password keeps your data secure. First of all, your data is always heavily encrypted both at our servers and while it's traveling to and from your device. Your data is not only protected by your Master Password, but also by your Secret Key. These two are combined in your device to encrypt your data and never sent over the internet. You can read a bit more about it here: https://1password.com/security/
If you have any questions or you'd like me to get into details for anything just let me know and I'll be glad to get into it!
