So basically i have had my phone for about 6 months and recently changed my password. I have since forgotten it. I have my thumb print that still works but i cant restart my phone as that will require a pin. I know i could factory reset it but i dont want to loose any data from my phone.
Go to the Google Device Manager https://accounts.google.com/signin/v2/sl… You should be able to change your lock screen password.
