Is regression considered to be a legit forecasting technique for timeseries ? "[Research]", "[R]"

When you search for forecasting techniques in Python, you mostly hear about autoregressive models and not about regression ..
Is it not right to use regression to forecast ? What is the main difference between using regression and autoregressive models ? When should we use one or another ?

Thanks in advance for your help
