1Blocker vs 1P, possible conflict

Hey Mark_Sealey,

Since 1Password for Safari is a “web extension”, it needs user permissions to be able to function within the browser. Our requirement to “allow access to all sites” achieves two things:

• The ability to scan (read) the page HTML to determine if it’s fillable. This also tells us where/when to inject the inline menu.
• The ability to autofill (write) to the site. While performing an autofill, it effectively changes the HTML. When you submit the autofill, it will allow you to authenticate it properly.

If you still have any concerns, I recommend going through this explanation of our security and privacy: About 1Password browser permissions .

I hope this helps! Let me know if you have any further questions.
