Are ‘Options’ still a thing?

This is the first time I've looked at WP dev in years.

Back in the day, I would set up 'options' so that I could set some of the content globally, like email addresses and phone numbers.

This time round Im trying to just do it with a plugin rather than editing the functions file (its just for a quick demo site Im trying to throw together)

I cant find much info online, has the name changed or something?
