Last bind off stitch?

[Hestermay]

I am a beginner and am ready to bind off (making a scarf). I have done it, but it was years ago. What do I do with the final stitch to keep it from unraveling?
Thank you!!

Break off (cut) the yarn and pull the tail through the remaining stitch and that'll do it!

Cut the yarn, leaving a few inches, then either pull it through the loop, or pull on the loop. Then take the tail and thread it through nearby stitches.
