Website v. App - providing credentials

Hello kdnavrat​! 👋

Welcome to the community and I'm sorry for the delayed reply. On the iPhone, AutoFill is specifically handled by iOS through an Apple feature named iOS Password AutoFill and 1Password only provides the data for the experience. Password AutoFill will match the apps that you use to your login items in 1Password by taking the associated domain associated with an app and comparing it against the website URL in your login items. If there is a match then Password AutoFill will offer to fill your login information.

If your login item is not being suggested for a particular app then you'll need to add the app's associated domain to your login item in 1Password. When you tap on the username or password field in an app you'll see the Password AutoFill prompt appear (above your keyboard), tap on the prompt and then search for the appropriate login item. Then, tap on that Login Item and tap Fill & Update Login. 

If you don't see Fill & Update Login when you search for and tap on a Login Item then it means that the developer of that app hasn't added an associated domain and there is nothing for Password AutoFill to use to match the app to a Login item in 1Password. This means that you'll need to search for the correct Login item each time that you sign-in to the app. You can also contact the developer of an app to request that they add a specific URL as an associated domain for their app.

Let me know if you have any questions.
