How to reset the password on Xiaomi Redmi 4X: all ways to unlock

The forgotten password on Xiaomi Redmi 4X is a problem that many users face, especially when the smartphone is locked and important data is left inside. Unlike the new models, the Redmi 4X (codename santoni) does not support unlocking through Face ID or fingerprint unless it is set up in advance. But the solution is: from official methods through Mi Account to technical solutions through Fastboot or Recovery.

In this article, we will discuss 5 proven password reset methods, including their pros and cons. Importantly, some methods require prior preparation (for example, linking a Mi Account or enabling debugging over USB). If you did not do this in advance, some options will not be available. Also note that unlocking through informal methods can lead to loss of warranty or data - this risk lies with the user.

How it works:

• 🔑 After 5 failed attempts to enter a password, the button Forgot the password will appear?.
• 📱 Click on it and select Unblock it with Mi Account.
• 🔄 Enter the username and password from your Xiaomi account.
