# This concern is inspired by "sudo mode" on GitHub. It
|
|
# is a way to re-authenticate a user before allowing them
|
|
# to see or perform an action.
|
|
#
|
|
# Add `before_action :require_challenge!` to actions you
|
|
# want to protect.
|
|
#
|
|
# The user will be shown a page to enter the challenge (which
|
|
# is either the password, or just the username when no
|
|
# password exists). Upon passing, there is a grace period
|
|
# during which no challenge will be asked from the user.
|
|
#
|
|
# Accessing challenge-protected resources during the grace
|
|
# period will refresh the grace period.
