Hi,
I would suggest you to refer to this article:
How can I sign in if my picture password fails?

Also, since you have forgotten text password, then recover Windows 8 Password via another Administrator account
If you have another user account with administrator privileges, including built-in accounts in Windows password, you can easily bypass other accounts' password using Lusrmgr.msc and Command Line.
Log on Windows with your administrator account. Click on Press Windows key + R, type
lusrmgr.msc and press OK.
When the Local users and Groups dialog appears, open the Users folder.
Right-click your user account and select "set password", type a new password and click OK.
According to Microsoft policy, Microsoft support engineers cannot help you retrieve passwords of files and features in Microsoft products that are lost or forgotten.
