FVE_E_PRIVATEKEY_AUTH_FAILED

The certificate is present, but the private key is unavailable

FVE_E_PRIVATEKEY_AUTH_FAILED occurs after certificate selection when BitLocker cannot obtain authorization to use the matching private key. Common boundaries include smart-card PIN entry, key-storage-provider access control, a missing private-key association, unavailable hardware, or a private key stored under another user or machine context.

Importing the public certificate again does not solve a private-key authorization failure. The certificate can look valid and trusted while the key needed to unwrap the volume material remains inaccessible.

Diagnostic checklist

Confirm that the selected certificate reports an associated private key and identify its key storage provider.
Test access under the same account, service identity, or recovery environment that invokes BitLocker.
For smart cards or hardware keys, verify device presence, PIN policy, middleware, and provider logs.
Do not export or weaken private-key permissions merely to make the operation succeed; correct the intended authorization path.
