Hi Moddrious,

thanks for the tip. First, I didn't sign in with Google account. And I don't want to lost the data. It would be much appreciated if you would give more details

My company bitcoin account was set with two-factory authorization.  The phone which receives verification code was locked because of wrong passcode. Actually, it was set by a former employee. So how it possible to remove or set the lockscreen passcode without losing any data? It is an old HTC One M7.

It is complicated for normal people and the price is high comparing to the currency. Confused about and fear of loss. i think this is the reason.
