This function allows you to enter your password, and then stores a slightly obscured version as an environment variable
the name of the password (and therefore environment variable) to be stored as an R environment variable.
Since passwords are annoying to enter, and you also don't want them stored as-is, even in an environment variable file, you can at least mask it a little bit. These will be saved in a place that only R uses, so if you use python you'll have to do that separately.
Add the following code to your website.
