1Password picking the wrong item to fill on iOS

Hello Arcane​! 👋

Thanks for the question! On iOS, it's not 1Password itself that handles filling in Safari and other apps but an Apple technology called iOS Password AutoFill. AutoFill is specifically handled by iOS and, in most iOS apps and browsers, 1Password doesn't control which suggestion you see when you tap on a field in a website or app since 1Password only provides the data for the experience.

If you're looking for a similar experience to what you see on the Mac then try the 1Password for Safari extension on iOS: Get to know 1Password for Safari on your iPhone or iPad

For apps on iOS that aren't Safari, the best option would be to create a collection that only includes vaults that contain your login credentials and not your wife's logins. You can read more about collections here: Use collections to create custom groups of vaults

Then you can limit iOS AutoFill to just the collection that contains your logins:

1. Open and unlock the 1Password for iOS app.
2. Tap the icon for your account or collection at the top left and choose Settings. (If you’re using an iPad, tap your account or collection at the top of the sidebar.)
   
3. Tap AutoFill. 
4. Change "Show filling suggestion from" to the collection that contains just your logins.

I hope that helps.
