    Permanently locking the secure element

    Hi,

    Just to clarify,

    the user guide states this:
    Warning: To avoid permanently locking the secure element card manager, do not try to authenticate over 10 times using incorrect keys. If the secure element card manager is locked permanently, you can use the applets in the secure element, but you cannot remove any existing or install any new applets to the locked secure element.

    I want to clarify is that is it that over 10 times in a row or not? Or maybe like add up to 10 times.

    Thanks

    AFAIK You can make 9 incorrect authentication attempts. If number 10 is incorrect then that is a permenant lock out. If number 10 is correct then the counter is reset.

    HTH,

    It is not possible.
    It's a feature to prevent brute forcing auth and a global platform specification.
    When a secure element chip is locked, it's forever.
