Set F1 Account Credentials — set_f1

Since October 2026, F1 live timing data (accessed through FastF1) requires an F1 account. This function stores your credentials in the F1_USERNAME and F1_PASSWORD environment variables, which FastF1 reads. The values are always set for the current R session. Optionally they are also saved in your user .Renviron file so they are available in future sessions.

Only the password authentication method of FastF1 is supported.

Usage

set_f1_auth(username = NULL, password = NULL, persist = FALSE)

Arguments

username: F1 account email. If NULL, you are prompted (interactive sessions only).
password: F1 account password. If NULL, you are prompted without echo using askpass::askpass() (interactive sessions only).
persist: Whether to also save the credentials to your .Renviron file. Default FALSE. Note that password will be stored in plain text in your .Renviron file if persist = TRUE.

Value

invisibly TRUE

Details

With persist = TRUE the password is stored in plain text in your .Renviron file (located by R_ENVIRON_USER or ~/.Renviron). The file permissions are restricted to the current user where supported. On shared machines consider setting the variables another way.

Examples

if (interactive()) {
  set_f1_auth()
}
