If you have not forgotten your password and you wish to change it from inside your account you need to follow these steps:
Go from your Personal accounts dashboard to the "Settings" section.
Then go to the "Security" tab, in this tab, you will find the "Reset Password" section where you will need to type your old password and then type and confirm your new one.
After doing so you will be asked to also insert a 2FA code and then click confirm.
