In its December 1999 edition, the Journal of the Evangelical Theological Society (JETS) published “The Authenticity of 2 Peter” – a 24-page article by Michael J. Kruger.
Kruger’s bottom line on the letter’s authorship (and therefore canonicity):
[W]e have no reason to doubt the epistle’s own claims in regard to authorship. [p. 645]
The fact that the early church finally accepted 2 Peter as fully canonical ought to add some degree of weight in favor of its authenticity. [p. 671]
