facetime is asking my old apple id

Hello WaelAlWirr,

Thank you for using Apple Support Communities. If you're getting prompted to enter your password for an old Apple ID, you're going to want to check your settings to make sure that Apple ID isn't populating there. This resource can guide you through which settings to check: What to do after you change your Apple ID or password - Apple Support

Mac with OS X Mountain Lion or later

Open the FaceTime app.

Select FaceTime > Preferences.

-If you're signed out, enter your updated Apple ID and password.

-If you're signed in with your previous Apple ID, select your Apple ID, click Sign Out. Then click Sign Out again when asked to confirm, and enter your updated Apple ID and password.

Check your iCloud settings:

If you're using macOS Catalina, choose Apple menu  > System Preferences, click Apple ID, then click iCloud. If you're using macOS Mojave or earlier, choose Apple menu  > System Preferences, then click iCloud.

-If you're signed out, enter your updated Apple ID and password to sign in. The data in iCloud will automatically appear on your device after you sign in.

-If you're signed in with your previous Apple ID:

1.) Click Sign Out. Depending on what iCloud options are turned on, you'll be asked if you want to make copies or delete iCloud data (Contacts, Calendar, Reminders, Bookmarks, Photo Stream) from your Mac. Your data will remain in iCloud and will be updated on your device when you sign in to iCloud again.

2.) Enter your updated Apple ID and password to sign in. 

If your old Apple ID isn't appearing in these specific settings, try checking your iCloud Keychain: View the information stored in a keychain on Mac - Apple Support

While viewing your iCloud Keychain details, try searching for the old Apple ID. If it populates anything, you might want to remove it.

We hope these steps are helpful. Cheers.
