TPM and Windows 11 Reinstallation

I want to ask something. I have a custom desktop pc with the gigabyte b550 aorus elite v2. I have created some passkeys, including of course the passkey for the windows hello pin.
My question is, what if I reinstalled windows ?? Does the reinstallation clears the tpm or not ??
If it doesn't, will the passkeys work correctly after (including the windows hello pin) ??
Or I have to delete them and recreated them again ??

Does it matter if I had a branded pc or a laptop or if I had a hardware tpm and not a software tpm (ftpm) ?

    depends on ur reinstallation comes deep with your local user's data , tpm maintain for sure ,

    a recovery attempt or windows update reinstall , would consider safe attempts

    a clean windows install would interrupt the passkey,

    make sure secure your account before windows install;

    lets check options as solution:

    create a password for microsoft account for a period of time,

    use an email for additional security,

    also authenticator app is the most secure way for any issues u might face with.

    after windows install, return your account security condition back to your previous state.
