How do you tie an application to a login later?

Hello arucious! 👋

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. Before we continue can you make sure that Password AutoFill is setup to work with 1Password:

1. On the Home screen, tap Settings.
2. Tap Passwords > Password Options.
3. Turn on AutoFill Passwords.
4. Select 1Password.

Then try to fill your login again using this guide: Use 1Password to fill and save on your iPhone and iPad

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.
