How to completely disable Google Smart Lock on Xiaomi phone: 3 working methods

Google Smart Lock designed to simplify access to your Xiaomi smartphone by automatically unlocking it in trusted locations or when connected to trusted devices. However, many users face situations where this feature becomes more of a vulnerability than a convenience. For example, if your phone unlocks in public places where you don't want it to, or if you're preparing to sell your Redmi or POCO device and need to completely remove all personal data links.

In this article, we will look at all the official ways to disable Google Smart Lock on Xiaomi in 2026, including hidden MIUI settings, which are not always obvious. It is important to understand that simply removing a feature through the menu is not always enough - residual data can be stored in the system cache.

What is Google Smart Lock and Why You Should Turn It Off

Google Smart Lock is an automatic unlocking system for Android devices that uses:

• 🔗 Trusted devices – unlock when connected to certain Bluetooth devices (earphones, smartwatches)
• 👤 Body recognition – unlocking when wearing oneself (e.g. in a pocket)
• 🔑 Saved passwords – automatic password entry in applications and websites

On Xiaomi smartphones (including the Redmi Note 12, POCO X5, Mi 11 and other models), this feature is integrated at the MIUI level, but managed through Google services.

⚠️ Attention: If you are using MIUI 14+ With App Lock, disabling Google Smart Lock may cause some applications to require password re-entry.
