I totally forgot it. When i try to connect with other acc write "Unable to sign in device due a recent pasword change. Please try to sign in again 24 hours after the password change was performed." How to login with other gmail acc?

Welcome.

You can't. Without those details, the phone will remain permanently unusable. It's a security measure.
