Go to the profile menu and click on your profile, as shown below. Once you are on the profile page, scroll to the bottom. Click on 'Change Password':
To update your password, your new password must be strong (i.e., includes numbers, letters and at least one special character). Click 'Update' or press Enter to confirm.
Once you’ve updated your password, a notification will appear in the bottom right-hand side of the screen. You’ll also receive an email confirmation that the password has been changed successfully.
