您好，密码可以修改不能删除。请参考TRM 9.5 Security Modes修改unseal key

Dear Star Xu, The default KEY(36720414) is generated during BQSTUDIO operation. After clicking UNSEAL, the KEY can be temporarily removed. If click the RESET, KEY is recover, How to return the Status for original BQstudio, thanks!

您好，出现这种情况是因为之前seal过，只要reset或者重新上电都会seal。想要使芯片处于unsealed状态reset也不会seal，请重新烧录固件。

您好,因为我烧录的这个固件烧录好了就是SEC1=1,SEC0=1,能否在这个固件基础上直接通过什么命令转为SEC1=0,SEC0=1,谢谢

您好，您下unseal command只能暂时解锁，reset或者shutdown 唤醒还是会seal，只有重新烧录unseal过的固件才能一直处于unseal状态。
