MySQL error #1045 on GoDaddy phpMyAdmin

After I made a new MySQL databases, I logged in to phpMyAdmin to test and got this message:

#1045 – Access denied for user ‘myusername’@’10.10.10.10’ (using password: YES)

What???

After couple attempts for a few hours, I decided to use a new difference password. Now it worked. It seem to me, there is a character in my initial password did not carry to or accepted by MySQL database.
