Changing Log in details.
There's a great shortcut for this. Log in using your current log in. At the top of the CRM menu you will see your name (highlighted in blue), click on your name and your personal details will be called up.
To change your email: edit the "Email" field
To change your password: enter a new "Password" and then retype it in the "Confirm" field.
In either case - remember to save! The next time you login you will need to use your new login details.
