How to unlock Xiaomi RedmiBook 9: All working methods (2026)

Fortunately, the manufacturer has provided several official and alternative ways to unlock – from a simple reset via Mi Account to radical methods like reinstall Windows. In this article, we will discuss all the current methods (including those that work without data loss), and also warn about the pitfalls of each of them.

It's important to understand that the way you unlock depends on which lock screen you see.

Before you start unlocking, check:

• ✅ Do you have access to an email or phone linked to a Mi Account or Microsoft account.
• ✅ Are there any backups of important files (on a cloud drive, flash drive, etc.).
• ✅ Are you prepared for the fact that some methods will lead to complete loss of data on the system disk.

2. Click on this link and the Xiaomi account login window will open.
3. Enter your Mi Account email/phone and password. If two-factor authentication is enabled, confirm your login via SMS or app.
4. After successful authorization, the system will offer to create a new password for Windows.

⚠️ Note: If you do not remember the data from Mi Account, do not try to find a password - after 10 unsuccessful attempts, the account will be blocked for 24 hours, in which case you will have to restore access through the official Xiaomi website (section "Forgot the password?»).

• 📌 The laptop was tied to the Mi Account before being blocked.
