No, your Internet Identity or personal information is not shared with dapps when you use Internet Identity for authentication. Here are the key points to understand:

1. Pseudonymous Identifiers: Internet Identity uses a different principal (a "pseudonym") for each dapp that you authenticate to. This means that each dapp sees a unique identifier for you, rather than your actual Internet Identity or personal information.
2. Privacy Protection: Since the pseudonyms generated by Internet Identity are different for each dapp, they cannot be used to track you across different applications. This ensures that your interactions with various dapps remain private and cannot be linked together.
3. No Personal Data Sharing: Internet Identity does not share any personal identifying information with dapps or even with the Internet Identity application itself.
4. Dapp-Specific Identities: Internally, users have a different pseudonym for each dapp, but a pseudonym for any single dapp is the same across all of the user's devices.
5. Authentication Without Personal Info: Unlike most authentication methods, Internet Identity does not require users to set and manage passwords or provide any personal identifying information to dapps or to Internet Identity.

This privacy-preserving approach is a key feature of Internet Identity, ensuring that users can authenticate securely without compromising their personal information or allowing their activities to be tracked across different applications on the Internet Computer.
