These will all be closely supervised, and not a single error is permissible.
It is impossible to allow someone to unlock a nuclear missile and then freely select the time and target for a strike.
What if someone wants to attack themselves? Could their own nuclear warhead blow up their own home?
As for that password, it is also extremely complicated.
The nuclear warhead's password device is designed for one-time use to prevent tampering.
Usually, there are three sets of passwords, corresponding to three different levels of authority.
One set for the supreme ruler, one for the highest governing body, and one for the commander of the nuclear forces.
All three sets of passwords must be entered correctly to unlock the missile, allowing the warhead to be activated and ready for use; otherwise, the warhead will automatically lock down.
