How to obtain previous (not the current) passwords from keychain on iOS?

I’m helping a person that does everything just in iOS. What happened is the person did a Password change in safari. It was one of the usual dialogues - enter current password and input new password twice. He used the keychain to fill out the first field and the generate safe password feature to fill the other. And after submission there was the popovers to update the password which he confirmed. Now, apparently on the form there was a checkbox or so that was required for the change so the website hasn’t updated the password. He can no longer log in as the old password is already updated on all his devices.

On a desktop machine i would have just restored the keychain. I thought there was a similar option for the iCloud backup - apparently not.

How can one recover from such a situation?

Solution 1:

The older passwords are unfortunately not stored in the keychain and cannot be recovered from the iCloud backup.

Your only option is to use the account recovery methods made available by that specific web site. For example many web sites allow account recovery through sending a password reset link via email.
