    I use it without localhost on MySQL 8.0.2 windows 64 bit. adding localhost as host on updateting the database solve the problem. Thank you

      I use win 10. I installed mysql. It generated a temporary password for mysql root. Then I created a user with some permissions. yesterday the userlogin was working fine. Today it shows the error.

      C:\myWebProject\mysql\bin>mysql -u myuser -p
      Enter password: *****
      ERROR 1045 (28000): Access denied for user ‘myuser’@’localhost’ (using password: YES)
