Hi drrajeev4u,
Happy Holidays! Are you having trouble logging in to the iTunes Store or Mail?
The first thing I would suggest is to go to the Apple ID website, sign in with your password, and confirm that the one you are currently using is correct. If you change the password here, you will need to change it in each of the settings for iCloud, iTunes & App Store, Mail, etc.

- Go to My Apple ID (appleid.apple.com).
- Click “Manage your Apple ID” and sign in.
- If you have two-step verification turned on, you'll be asked to send a verification code to the trusted device associated with your Apple ID. If you're unable to receive messages at your trusted device, follow the guidelines for what to do if you can't sign in with two-step verification.
- Click "Password and Security".
- In the "Choose a new password" section, click Change Password.
- Enter your old password, then enter a new password and confirm the new password. Click Save when done.
The next time you use an Apple feature or service that uses Apple ID, you'll be asked to sign in with your new Apple ID password.
Next, restart your iPad. If you still get the prompt, then you may need to reset the device.

If the issue still persists, then re-entering the password information for each of the services above would be the next thing to try. You can do this from the Settings app on the iOS devices.
