Most browsers now store passwords in secure 'keychains' - and so your device can autocomplete your password entry. That's great, until you change your password, but your keychain is still using the old one in its keychain.
You will need to delete that old password keychain from your browser, login with your new one and then save that as your new remembered password.
To clear that old password, if you are not offered a chance to update it when you next go to Educa, you will need to clear your browser's cache, your browser's temporary storage memory. How to do this varies by browser.

In Google Chrome you can delete the remembered password.
Under the "Chrome" tab, open Preferences,
