What Form 2848 is
irs.gov says to use Form 2848 to authorize an individual to represent you before the IRS, and that the individual you authorize must be a person eligible to practice before the IRS. It also says that authorizing a qualifying representative allows that individual to receive and inspect your confidential tax information. The form itself carries a caution that it will not be honored for any purpose other than representation before the IRS. RepeatForm cannot tell you whether to appoint anyone or whom.
