I want a command where a player can change his id

For ex

If a player types /setmyid 100

the player's id changes to 100

I have a doubt
Is it possible?

It's not possible.

It's not possible, but you can create your own Id System (sided Identify's)

I've seen something like that here

i hope this isn't a kind of advertisement
