Sign in to your account

Locate the 25-character key

Frequently Asked Questions

What is a 25-character Microsoft recovery code used for?

It is typically used as a BitLocker recovery key to unlock an encrypted Windows hard drive, or as a Microsoft Account recovery code to regain access to your Microsoft account if you lose your two-factor authentication methods.

Why is my Microsoft account blocked for 30 days?

Microsoft imposes a mandatory 30-day waiting period when you request to replace all of your security information (like an alternate email or phone number). This is a security measure to prevent hackers from locking you out of your own account. During this time, you can still access basic services like Outlook from familiar devices.

Can I bypass the 25-character BitLocker recovery key prompt?

No, BitLocker encryption is designed to be highly secure. If you cannot find the 25-character recovery key in your Microsoft account, Azure AD, or on a physical backup, you cannot bypass the screen and may need to format the drive, which will result in data loss.

Will I lose my files if I can't find my Microsoft recovery code?

If it is an account recovery code, you can wait out the 30-day security period to regain access. However, if it is a BitLocker recovery key and you have no backup of it, the files on the encrypted drive will remain permanently inaccessible.
