Password management in R and Python

in R

Option 1 using source

create pass.r and keep it yourself

Code

pass.r

pass1='123'

source the pass.r in the main code

Code

source('pass.r')
pass1

[1] "123"

Option 2 Use Environment variables

open /home/.Renviron

Code

usethis::edit_r_environ()

save following password in .Renviron

Code

fake_userid = "username"
fake_pwd = "password"

get it back

Code

Sys.getenv("fake_userid")

[1] "username"

Code

Sys.getenv("fake_pwd")

[1] "password"

Option 3 using keyringr package

Code

pak::pak("keyring")

Code

library(keyring)

Code

# Interactively save a secret. This avoids typing the value of the secret
# into the console as this could be recorded in your `.Rhistory`
key_set("account_fake_001")

Code

# Later retrieve that secret
key_get("account_fake_001")

in Python

Option 1 using import

create pass_file.py and keep it yourself

Code

pass_file.py

pass1='123'

call pass_file.py with import

Code

from pass_file import *
#from pass_file import acct
pass_w

'123'

Code

acct_w

'222'
