javascript - HTML One time use page -


i want on website once user signs up/requests password recovery email address of account have requested sent email 1 time password set page time-out.

the way can think of doing having database table random access key , expire time.

  • an incorrect key , page doesn't run.
  • if key correct time has expired offer send another.
  • if both correct on page access remove key database table.

unless using wrong key words can't find on google.

is secure method or there better way of doing it?

sounds me.

i 2 cases:

1) "url-key thingie" not in db, or in db expired ---> process "page either unavailable or expired, recheck email."

2) link hits active timelimit reference, display page via ssl. use pdo.

including captcha not bad idea. google captcha.
