mysqldump Error 1045 Access denied despite correct passwords etc

Question

This is a tricky one, I have the following output:

mysqldump: Got error: 1045: Access denied for user \'root\'@\'localhost\' (using password: YES) when tr

Answer 1

Don't enter the password with command. Just enter,

mysqldump -u  -p  > .sql

Then you will get a prompt to enter password.
