You just copied/Pasted the code and didn't even comment it
Your "Method" won't work with every site
Because you can't guarantee that the Log In button Value will be "Log In"

You just change Log In To your needs...

You can get the Html element "Any thing not only buttons" by various ways
Title
Src
Name
Alt
Type
Value
etc
So i was just pointing that out 😊
