Password Card

This feature is only available in ESP-DASH Pro

A secure input card component for collecting and storing sensitive text data like passwords or secrets. Masks input values on the dashboard for enhanced privacy and security.

Initializer

/* 
  Password Card
  Valid Arguments: (ESPDash dashboard, Card Type, const char* name)
*/
Card card1(&dashboard, PASSWORD_CARD, "Test Pass");

Callback

Password card requires a callback function which will be called when we receive a input from our dashboard. In setup block, we will be calling our attachCallback function and provide a lambda (callback) function with a const char* (character array) argument.

/*
  We provide our attachCallback with a lambda function to handle incomming data
*/
card1.attachCallback([&](const char* value){
  Serial.println("[Card1] Password Card Callback: "+String(value));
});

Updater

💡

Password card doesn’t require any updater as value is not passed back to dashboard.
