@Stephonomon, this sounds like it's related to GitHub, and not specifically to REDCapR. So the existing posted solutions should address this.

My favorite is by Jenny Bryan & Jim Hester: https://happygitwithr.com/github-pat.html#step-by-step

And here's one adapted from the issues of the 'remotes' package that is very similar (r-lib/remotes#330 (comment)). I'd still use usethis::git_sitrep() (as described in the book above) to verify the PAT is set.

1. Login to GitHub.com
2. Create a new personal access token (Settings > Developer settings > Personal access tokens)
3. Copy the token to your clipboard
4. In RStudio, run usethis::edit_r_environ()
5. Store the token in R, save, and restart R.

   GITHUB_PAT=xxxx

6. Run remotes::install_github("OuhscBbmc/REDCapR") or remotes::install_github(repo="OuhscBbmc/REDCapR", ref="dev")
