No serious suggestions per say, but some occultists have written of gates and guardians that were aggressive or took no notice of someone until they performed certain signs and then were allowed to pass. This is mirrored by teachings of the Loa, found in Obeah, Voudoo and Turtle Island Shamanism, the names change but the symbols and aspects are pretty consistent.
The signs generally correspond to Mudras in Vedic and traditional Chinese teachings (as well as ninpo), sometimes there are passwords or Mantras, but I cannot address that. I can say that there are teachings in some Taoist/Chinese religions of these same gates, guardians and even spiritual armies and kings etc. Such teachings are found across the world in most ancient religions... for one reason or another.
The first major sign/mudra is Añjali.

I would start there if I were going to try such a thing.
It is said that the names of the entities can also serve as passwords.
I don't share this as a believer or a non-believer, I am just a clueless student of the mystery itself.
Here is a poem however about the keeper of the 1st gate according to some teachings:
oh papa,
at the cross roads,
are you old,
or are you young?
with your hat
and with your cane
two snakes of the world
the waters and the stars
the winds, they are yours
the small dog is barking
master of the gate
pachamama is your wife
are you ever not near?
are you a force of nature,
or is nature a force of you?
There are also signs called veves worth looking up, your mind can form them, you can draw them with "light" or you can even use hard copies you make yourself.
I would not mess with this stuff though, it does scare me, and some of the "entities" require blood and or sacrifice.
You will notice that a lot of groups use and invoke Christ, modern ayahuasca religions for example often do. There might be a protective reason behind this. There is a story of an occultist who worked with these spirits (perhaps the same as Demons according to some) and then tried to make a woman fall in love with him and the demon told him that he could not, because she was protected by Christ and the sorcerer (Andean shaman) then converted to Christianity. This story plays a role in Andean Shamanism still.
these kind of spirits also play a role in the dance Diablada
One might keep in mind that the christian symbolism in this dance is what the anthropologists call
protective coloration, or the adaptation of the symbolism of the invading and intolerant culture to allow the continuation of banned archaic practices. Saint Peter, the Virgin Mary and others in this symbolism are NOT the same as the personages or deities in Catholicism, the case here is identical to that of the Loa (
Lwa - Wikipedia) where the same catholic symbolism is used to represent the Loa which predate Christianity.
Or perhaps this is all silly and the deities are psychological manifestations of unresolved issues that are deeply personal and incapable of being understood or dealt with in any other way.
Like I wrote: I am clueless. However:
I've seen the blood work too many times to say I think there isn't something to this.
Needless to say I don't teach my children this stuff.
