How to fasten off glove finger?

When you finish knitting the end of a glove finger (the finger tip) and the instructions tell you to thread the yarn through the remaining stitches and pull tight, is there a good way to fasten off the yarn to avoid a hole? Thanks for any help.

What I do is to pull it tight, run it through a couple of stitches again, and then put the tapestry needle down through what’s left of the hole. I flip it inside out and attach the yarn on the inside by weaving it down the finger a bit.
