In the top right of your screen, there will be a person icon, this is where you will find your profile. You can change your personal information and update your password here.
You can also determine what notifications you want to receive in your inbox.
Please note, you receive email notifications on a project related actions taken by the client, any invoices paid, a contract approve or messages sent in the message center in addition to the bell option notifications. Hence, you might want to consider turning off any of these if you are being too spammed by email notifications or you choose not to receive these in your email.
