Hi, I’ve changed my Apple ID password and I still receive authentification request even if I introduced the new password. What can I do further in order to disappear the request. Thank you, Camelia

I guess, you already completed these steps?

What to do after you change your Apple ID or password - Apple Support

It helped some users, to log out in the settings for Apple ID, restart the phone and log in again, using the Apple ID and the newly created password.

Then you should try to contact Apple ID Support about that. Only the can look into your personal settings:

Get Apple ID Support
