For got both username and password for google account on my android tablet

if you have a google account, you can do this option

1. When you try different patterns and unable to unlock your phone in five attempts. Then a message pop-up and shows two buttons "next" and "try again".
2. Now click on "next" button and you see two options for unlocking phone. One is answer the security question and the second option is to provide Google account details.
3. Mostly people don't set a security question. But if you set it then simply answer the question and unlock your device quickly. Otherwise check the Google account option and click "next".
4. Now provide your Google account username and password attached with your device and click on "sign in".
5. After that you are directed to choose new pattern and now you can unlock with this pattern.

if you don't have your google account, you can do the recovery option, but you will lose all your data in there

1. Power off your phone.
2. Now press Volume up, power and home button at the same time and wait until your device starts.
3. When you see logo screen release the power button and keep pressed the other two buttons.
4. Now your screen shows android system recovery and there is a list. Use Volume up or down keys to select option from the list. And select factory reset option and then press power button to let the action begin.
5. Now it asks you for confirmation, select "yes".
6. After factory reset completes, it again shows you android system recovery screen. Now select reboot option and after restart it will not ask you for pattern.

its brand new and you forgot everything already if you did the google mail password assist then open that if dont know that or didnt do it can try provider for assistance and most lockouts are either 1hr or 24hr

On the Google sign-in page, click the "Need help?" link.

Your title of the question says u lost your google user+pass? but the description talk about something else i notice, but to fix the google issue go to google to sign in then click FORGOT PASSWORD or USERNAME then u put in your email address and go from their, this will get you back into your google account, if the pad not working use another PC to do this. If the pad won't work google how to do system restore on ANDROID 10, or find the manual for your model and read how to do this. If you can get in i'd backup any important files first...save favourites/bookmarks if u need to or any profiles, as u may loose all apps and have to reinstall worst case...

So if I understand you correctly you have attempted to access your Google account and after too many attempts you are locked out, correct?
Step 1. Goto http://www.google.com/ click on "Sign In"
Step 2. Click on "Can't access your account..."
Step 3. Follow the steps to restore your account, they are quite simple.

If you have a Kindle that is locked and you forgot the password, you have to do a full restore using Kindle Fire First Aide, this is the only option for a locked Kindle.

too many pattern attempts

Wait a while, and if it still isn't working try to use a new google account.

you have to ring the manufacturers and get them to make you a google account same thing happened to mine
