Hello Jason,
The one-time passcode requirement you’re seeing is not part of the standard BitLocker recovery process. Normally, if BitLocker is asking for a recovery key, you can retrieve it directly from your Microsoft account at https://account.microsoft.com/devices, under the “BitLocker recovery keys” section, without needing any OTP. If the portal is prompting for a one-time passcode, that usually indicates that your account has additional security policies enabled, such as Azure AD Conditional Access or MFA enforcement, which require verification before releasing sensitive information like recovery keys.
Since you’re not receiving the email, the first step is to confirm that your Microsoft account actually has the BitLocker recovery key stored. Log in from another device and check the “Devices” page. If the key is not listed there, it means the recovery key was never backed up to your account, and you’ll need to check other possible storage locations: printed copies, USB drives, or your organization’s Azure AD portal if this is a work-managed device.
If the key is listed but you’re blocked by the OTP issue, then the problem is with your account’s security verification. In that case, go to https://mysignins.microsoft.com/security-info (mysignins.microsoft.com in Bing) and verify that your recovery email and phone number are correctly set up. If the email is not arriving, try adding an alternate method (SMS or Authenticator app) and use that to complete the verification. If this is a work device, your IT administrator may have restricted recovery key access, and you’ll need to contact them to release the key.
Unfortunately, without the recovery key, BitLocker cannot be bypassed or disabled. The only supported way to unlock the drive is with the correct recovery key. If none of the above methods work and you cannot access the recovery key, the only option is to wait for Microsoft account recovery to complete or escalate through your organization’s IT support if it’s a corporate-managed machine.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
