User vault security

We use Devolutions server as our repository for company systems.

We would like to use user vaults to secure personal information, but some users voiced their concerns that although the system seems secure, how can they be assured that a malicious administrator couldn't access their personal information, since it has the ability to change settings or in worst case scenario change the user password or remove 2FA configurations.

Is there support on Devolutions server to secure the user vaults against this kind of scenario? (ex: personal encryption key, unremovable OTP, Yubikey, etc...)
