While trying to repair a Windows 10 OS, a technician receives a prompt asking for...

A recovery key is a code that can be used to unlock a BitLocker-encrypted drive when the normal authentication methods (such as password or PIN) are not available or have been forgotten. BitLocker is a feature of Windows that encrypts the entire drive to protect data from unauthorized access. If a technician is trying to repair a Windows 10 OS that has BitLocker enabled, they will need the recovery key to access the drive and continue the OS repair. SSL key, preshared key, and WPA2 key are not keys that are related to BitLocker or OS repair.
