To change the password, click the icon on the right top corner of the page and choose Settings:
Choose the Security section and click Change password.
The system will ask you to type your current password first and then the new one. After you confirm the password change you can choose to logout from other devices where you're currently logged in in case you feel your account has been compromised.
You’ll see a notification that your password has been successfully changed and you’ll be logged out of the platform:
You have successfully changed your password!
