How to change default Passkey provider back to system?

Hello cipher! 👋

Thanks for reaching out. 1Password has implemented iOS 17's passkey API, which Apple has provided for third-party apps. Users get to choose whether they use Keychain or a third-party password manager for the purpose of saving and signing in with passkeys through iOS Settings:

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

This isn't something that a website would be able to override or change for the user. As a user, I wouldn't want to have a website have the ability to save passkeys in Keychain when I've explicitly turned that functionality off.

my website needs to access system Passkey provider instead of 1Password. Because 1Password Passkey does not act 100% the same as system default. 1Password tends to 'update' a previous passkey instead of 'create' a new one when the user trys to.

Can you clarify what you mean here? 1Password follows the passkey spec as defined by FIDO. Users should be able to save a new passkey for your website. If there are issues happening with 1Password's implementation of passkeys then I would be happy to file a report with our development team.

I look forward to hearing from you.
