Greetings!
We appreciate your post in the Apple Support Community. Here are some steps you can take to resolve the issue:
Visit the Apple ID website and click on "Forgot Apple ID or password?". Follow the prompts to reset your password. If you've enabled two-factor authentication, ensure that you can access a trusted device to receive the authentication code. If you continue to face issues even after resetting the password, it's best to directly contact Apple Support Tel.: 0800 6645 451 (DE). They can provide specific information about your account and assist you further.
Please refrain from sharing personal details such as your Apple ID or other sensitive data on public forums or platforms. It's essential to safeguard your information.
For English speakers, we have a dedicated community right here: discussions.apple.com.
Since your message is in English, we warmly invite you to join us in that community.
Thank you!
