    Do you have an archived iTunes backup made while your phone was on 11.2.6?

    As far as I know, that's simply not possible. FaceID data is only ever kept on your device inside the Secure Enclave and is never backed up to the cloud, or even any local iTunes connected computer. When you reset your device to downgrade, that FaceId data will be deleted and you'll have to start again.

    Again, these are the perils of using a beta.

    Edit: From the Apple FaceID Security Guide

    Face ID Diagnostics

    Face ID data doesn’t leave your device, and is never backed up to iCloud or anywhere else.

    Doesn’t matter. Even if you had a backup, that’s not restored.

    Been there, done that.
    If you have important messages, just back-up everything before downgrading to v11.2.6
    All will be gone. You may use 3rd party app to retrieve it.

    You missed the bit where the OP wishes to also backup FaceId - which seemingly is impossible to do.

    As far as I know, it's seemingly impossible:oops: Maybe you could wait the final release of iOS 11.3.
