Daughter has changed that password in her Huawei P10 Lite. Unfortunately, she did not notice. She can't log in anymore? What to do? Who is responsible?
There's a super pin to unlock for these cases. That should be found in the contract documents.
Sometimes there's a password forgotten button, then you can reset the password via Google. If that does not work, only a hard / factory reset will help.
Who is responsible
Your daughter
Where a hard reset would bring nothing if the daughter does not know their Google data. Because after a hard reset the theft protection starts.
I know, as I wrote above, you need the Google data.
