Play on load (automatic log in)

Is there a way to play the macro when a page loaded ?
Or there is a way to trigger the macro automatically ?

The answer is: “It depends”… Is this just for one specific website, or do you want to have many macros that “play on page load”?

So should this work kind of like the Lastpass password manager, but with real macros that do actual work, instead of just filling in login and password?

Its like an auto login chrome extension but , doing more than just fill and press login
