Hi mad4dogz,
Welcome to the Support Communities! So that I can understand your question, where are you trying to log in when the password request happens? Are you at iCloud.com, or using email, or iTunes, FaceTime or iMessage? Are you getting an error message that states to change the password, or is it that when you enter your password, you can't get past the log in screen? Are you working with a Mac, an iPhone or iPad, or a PC?
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 I mentioned above.

- 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.
If you are using an iOS device (iPhone, iPad or iPod touch) - I would first restart the device. 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; System Preferences on your Mac; or iCloud Control Panel on a PC.
Sorry this information is somewhat vague, but without knowing the details above, it will hopefully give you some ideas for troubleshooting the issue.
