“by the authority of” is NOT found at all in the KJV. Whereas, “in the name of” is found 64 times.
Furthermore, the word translated into English as name in Matthew 28:19 is Strong's G3686 - onoma
Strong’s Definitionsὄνομα ónoma, on'-om-ah; from a presumed derivative of the base of G1097 (compare G3685); a "name" (literally or figuratively) (authority, character):—called, (+ sur-)name(-d).KJV
Translation Count — Total: 229xThe KJV translates Strong's G3686 in the following manner: name (193x), named (28x), called (4x), surname (with G2007) (2x), named (with G2564) (1x), not translated (1x).
While “authority” is listed as one way that Stong’s # G3686 “can be used”, it is interesting to note that Strong’s # G3686 was NEVER used in the KJV as “authority”. So, no serious Bible Student should be trying to put that square peg into a round hole.

This is how it appears in the King James Version. In some of the other versions, it reads, "in the name of the Lord Jesus". Let me ask you this question.
