How can I configure captive portal to also display the reset password immediately
is the password reset or change, if the reset, how do you validate the user is correct, ? if you show the password change with out validation that will be security risk i see, until you validate the user is correct or not, by form of validation, so we use email or can be done SMS i guess.
check below URL reset password :
