The password can not be bypassed, otherwise, it would not be a very secure security mechanism. The only recourse you have is to do a hard factory reset, HOWEVER, please consider that a factory reset will reset your Samsung Galaxy Tab to factory settings and your all data on the device will be removed.

The steps to do a hard reset are as follows:
1. With the device off, press and hold Volume Up and Power button.
2. Release the Power button when you see the Samsung logo, continue to hold Volume Up until the recovery screen appears.
3. Use the Volume buttons to navigate the menu and select wipe data / factory reset. Press Power to continue. The Galaxy Tab should then go through the hard reset process.
4. When formatting completed, navigate to select Reboot system and press Power. The Samsung Galaxy Tab is back to the factory
