FVE_E_POLICY_PASSPHRASE_TOO_SIMPLE

FVE_E_POLICY_PASSPHRASE_TOO_SIMPLE The proposed password/passphrase does not meet the complexity requirements imposed by effective BitLocker policy. This is a policy validation failure, not an indication that the volume is damaged.

What to check

  • Review the required complexity rule for the specific drive type.
  • Choose a passphrase that meets the enforced character and complexity requirements.
  • If the device is managed, verify the resulting policy after Group Policy or MDM refresh instead of changing a local setting that will be overwritten.
