[pbs-devel] [PATCH proxmox-backup 2/3] Revert "ui: window/Settings / WebAuthn: add browser setting for userVerificationo"

[Dominik Csapak <d.csapak@proxmox.com>]

even if the options *could* be set in the frontend, the backend
actually has to do validation of those settings, thus we should not
make that a browser setting

additionally, having the value 'preferred' does not actually make sense,
since it does not add any security (the backend currently skips the
user verification check then)

This reverts commit aca4c2b5a9de23f7cafab92da0f88123f4ca5d8c.
