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.

1) You can reset factor to your HTC phone, these will wipe your data.
2) Login in your account via Google account if you have.
3) Try some Android screen removal tool to unlock your screen password.
