Good idea, because only a regularly changed password is a secure password.
You can directly jump to the Change password page
Or: Log in to RPLAN Connect and move the mouse to the upper right to your email address. A drop-down menu appears; click the
User Profile option. On the user profile page you'll find the
Change password option. Click it to open the fields for the new password, enter it twice and save it (and remember it). That's all.
