Still not able to change the PIN code for Passkeys Manager

For passkeys, there is no supported PIN-change flow in the passkey management pages described here. The available actions are to view, rename, or remove saved passkeys.

If the PIN tied to a passkey is no longer usable, the supported recovery is:

1. Sign in using another available method.
2. Create a new passkey.
3. Remove old or invalid passkeys from the account and from the place where they were saved.

Relevant places to manage or remove passkeys:

• Windows 11 device-bound passkeys: Settings > Accounts > Passkeys
• Personal Microsoft account passkeys: Microsoft account Advanced Security Options
• Work or school account passkeys: Security info at mysignins.microsoft.com/security-info

Important details from the documented behavior:

• If a device was replaced, a new passkey must be added first, then old passkeys can be removed.
• If the passkey was stored in a synced credential manager, a new device usually does not require creating a new passkey; signing in to the credential manager is enough.
• If the authentication method changes, such as changing the PIN or biometric method on Android, the passkey can become invalid and a new passkey must be created.
• If Windows shows only delete/remove options for a saved device-bound passkey, that matches the documented management options.

If sign-in is blocked because the passkey is no longer valid, use one of the alternative sign-in methods offered, then remove the outdated passkey and set up a new one.
