When you register for a myCBDR account you are sent a temporary password that will look similar to T&nf4#2Lh5.
If you copy and paste this temporary password into your browser, it will sometimes add an invisible extra character on the end. After you copy, backspace once and then click submit and it will work.
The exception is if you wait too long to use this temporary password, it may expire and not work. If this happens, click the Forgot Password link to receive a new temporary password.
Once you are logged in, you will be asked to re-enter the temporary password then create a new password. Once a year you are required to change your password and you cannot use any of the 12 previous passwords.
