I forgot my password to unlock my Samsung Galaxy 10.1

"NOTE: You may have to wait 30 seconds-1 minute when performing each step.

If you don't want to lose DATA there may be a ""Forgot password?"" option in which case google will reset the password via your email. If this option is not there then follow these steps.

To perform factory/hard reset please follow those steps (you will lose everything):

1. Turn the power off.

2. Press and Hold the Volume Up and Power button at the same time.

3. When the start up screen show (Samsung logo displays on the screen), release all the buttons.

4. Use the Volume Up/Down button to navigate to ""wipe data/factory reset"", select with Power button

5. Select ""wipe data/factory reset""

6. Select ""Yes -- delete all user data""

Allow several minutes for the factory data reset process to complete.

7. Select ""reboot system now""

Allow several minutes for the reboot process to complete."

Press Power Botton and Volume Down Button Together

You can unlock a device remotely if you have it registered to a Samsung account. On another device, go to findmymobile.samsung.com and log into your account. (I was able to reset my Samsung account password using the link before proceeding.) On the next screen, click Find, then More, then Unlock My Device. I had to reset all passwords, PIN, etc for the tablet, but so far it looks like all my downloads and other personal data is intact. Hope this helps!

"I forgot password, and the Samsung tab S was left in corner more than a month.

I followed all instructions nothing worked.
