API : how to connect user without using "Sign the user in"

Hi everyone !

i’m trying to create some API path for my clients.

My problem is when i uncheck “ignore privacy rules” in my WF setup i can’t retrieve the data of my get calls cause i don’t authenticate the user.

the trick is that to authenticate the user i need to use the “log the user in” action, but this action need the Email and Password of the user and i don’t want to use this.

Is there any other method to authenticate my user ? Like using a Token or The unique_id of the user ?
