Forgetting your password is frustrating, but luckily there’s a really easy way to reset the password.
i. Reset a PIN lock
If you forget the 4-digit PIN that is used to unlock your phone, you can tap the Forgot password key on the lock screen. It brings you to a screen where you’ll be asked to enter your Google Account password.
If you don’t have your Google Account associated with your phone, you’ll be asked to enter your Xiaomi Account password instead.
Upon successful authentication, the Screen security will set to None.
ii. Reset a Pattern/Password lock
After 5 wrong attempts, you should see the Forgot password button appears on the screen.
Tap the Forgot password button, then enter the password for the Google Account that you’ve signed in on your phone to reset the Screen security to None.
If you haven’t had your Google Account signed in, then you’ll be asked to key in your Xiaomi Account password, assuming you’ve signed in your Xiaomi account, to reset the Screen security to None.
iii. Reset your Screen Lock (Pattern/Password/PIN) using Find Device
Xiaomi’s Mi Cloud comes with a feature called Find Device, which lets you track and remotely set a PIN to lock your lost phone. Hence, making use of this feature, you can reset your forgotten PIN/Password/Pattern with a new PIN.
