I tried to put a new password on my phone because my mom changed my password and wouldn't tell me because I got a C+ on my report card. She acts like she pays the bill for it.

Get into the phone change the password to a pin like 1234. Go back to find my phone and set the lock phone on the find my phone to the same pin you already have your phone set to. Used LGL21G

The key to unlocking and removing this is hard for the galaxy note 3. I had to reset the password multiple times because with the note 3 if you put a passcode it wont let you,but if you put a password it will always be wrong...So the only solution is putting in the orignal password instead of the device manager.

You can remove the password from Settings -> Security -> Screen lock, enter the specified password and choose your desired new lock type. If you previously didn't have a PIN, Pattern or Password lock, use the Slide option.

I have played with Android device manager and I have blocked my phone. I have deblocked but everytime my phone enters into standyby it apears me the message "locked by android device manager" and I have to enter the password again.

Yes. I had to perform a factory reset, because I think I've tried everything. Changed the password on android device manager and blocked again. It appeared the new password, I have deblocked again, went to Settings -> Security -> Screen lock entered the new password and I choose None. I restarted the phone but it keept appearing me the text "locked by android device manager". After the phone ringed on phone that I set on androide device manager I could enter the phone without entering the pasword.
