1Password offers several ways to manage autofill options on websites, allowing users to customize their experience and reduce frustration. On computers, users can choose from three options: "Fill anywhere on this website," "Only fill on this exact domain," or "Never fill on this website." For sites visited infrequently, users can add the site URL to 1Password and set it to never show a prompt. Users can also clear password prompts manually by clicking inside a field and then clearing the message. On mobile devices, users have two main settings: Autofill and Show filling suggestions, which can be turned off to reduce intrusiveness while still allowing access to stored logins and passwords. By using these options, users can make their 1Password experience less intrusive and more tailored to their needs.
